Description of problem: I'm trying to rebuild mrpt in f20 and f21, and it looks like arm gcc is hitting an error that i686 and x86_64 versions aren't. You can view the build logs at http://koji.fedoraproject.org/koji/taskinfo?taskID=5928632 The i686 and x86_64 builds finish without issue, but the arm version segfaults consistently at the same point: cd /builddir/build/BUILD/mrpt-1.0.2/build/libs/slam && /usr/bin/c++ -DDISABLE_OPENNI -DEIGEN_USE_NEW_STDVECTOR -DEIGEN_YES_I_KNOW_SPARSE_MODULE_IS_NOT_STABLE_YET -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__ -Dmrpt_slam_EXPORTS -DvtkFiltersStatistics_AUTOINIT="1(vtkFiltersStatisticsGnuR)" -DvtkRenderingCore_AUTOINIT="4(vtkInteractionStyle,vtkRenderingFreeType,vtkRenderingFreeTypeOpenGL,vtkRenderingOpenGL)" -DvtkRenderingVolume_AUTOINIT="1(vtkRenderingVolumeOpenGL)" -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard -isystem /usr/include/opencv -isystem /usr/include -pthread -I /usr/lib/wx/include/gtk2-unicode-release-2.8 -isystem /usr/lib/wx/include/gtk2-unicode-release-2.8 -I /usr/include/wx-2.8 -isystem /usr/include/wx-2.8 -Wno-deprecated -isystem /usr/include/pcl-1.7 -isystem /usr/include/vtk -isystem /usr/include -isystem /usr/include/freetype2 -isystem /usr/include/libxml2 -isystem /usr/include/python2.7 -isystem /usr/include/eigen3 -isystem /usr/include/qhull -Wall -Wno-long-long -Wno-write-strings -Wno-variadic-macros -pedantic -pthread -std=c++11 -fopenmp -fPIC -I/usr/include/eigen3 -I/usr/include/eigen3/unsupported -I/usr/include/opencv -isystem /usr/lib/wx/include/gtk2-unicode-release-2.8 -isystem /usr/include/wx-2.8 -I/usr/include/vtk -I/usr/include/freetype2 -I/usr/include/libxml2 -I/usr/include/python2.7 -I/usr/include/pcl-1.7 -I/usr/include/qhull -I/usr/include/suitesparse -I/builddir/build/BUILD/mrpt-1.0.2/. -I/builddir/build/BUILD/mrpt-1.0.2/build/include/mrpt-config/unix -I/builddir/build/BUILD/mrpt-1.0.2/libs/slam/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/bayes/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/graphs/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/vision/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/scanmatching/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/maps/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/obs/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/opengl/include -I/builddir/build/BUILD/mrpt-1.0.2/libs/base/include -o CMakeFiles/mrpt-slam.dir/src/slam/CMetricMapBuilderICP.cpp.o -c /builddir/build/BUILD/mrpt-1.0.2/libs/slam/src/slam/CMetricMapBuilderICP.cpp /builddir/build/BUILD/mrpt-1.0.2/libs/slam/src/slam/CMetricMapBuilderICP.cpp:629:1: internal compiler error: Segmentation fault } ^ Please submit a full bug report, with preprocessed source if appropriate. See <http://bugzilla.redhat.com/bugzilla> for instructions. Version-Release number of selected component (if applicable): gcc armv7hl 4.8.1-6.fc20 How reproducible: This bug happens consistently in f20 and rawhide when building the mrpt package. Steps to Reproduce: 1. Submit mrpt-1.0.2-1 for building on koji 2. 3. Actual results: Segmentation fault during build Expected results: Finished build
Override CFLAGS and see if it goes away at -O1 or -O0? --Kyle
Thanks Kyle. I overrode the cflags to pass -O1, and the build completed without an internal compiler error. So as a work-around I'll leave mrpt at -O1 for now. The bug is still reproducible at -O2, so I'll keep this bug open.
Please provide the preprocessed source (add -save-temps to the above compilation line and attach CMetricMapBuilderICP.ii it creates).
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
