Description Ben Webb 2016-06-22 18:33:19 UTC 
Created attachment 1171028 [details]
Preprocessed source dumped by g++

Description of problem:

g++ fails with an ICE while trying to compile some SWIG-generated wrapper code (preprocessed source attached). This is on latest patched Fedora 24.

Version-Release number of selected component (if applicable):
# gcc --version
gcc (GCC) 6.1.1 20160510 (Red Hat 6.1.1-2)


How reproducible:
Always.

Steps to Reproduce:
1. Download latest srpm from http://integrativemodeling.org/nightly/download/ (I used the .el6.src.rpm)

2. Rebuild with rpmbuild or mock

Actual results:
Compilation fails with output similar to the following:

/builddir/build/BUILD/imp-20160622.develop.8795f4a/build/src/algebra_swig/wrap.cpp: In function ‘PyObject* _wrap_DenseDoubleGrid3D_add_voxel(PyObject*, PyObject*)’:
/builddir/build/BUILD/imp-20160622.develop.8795f4a/build/src/algebra_swig/wrap.cpp:69846:33: internal compiler error: in assign_temp, at function.c:961
       result = (arg1)->add_voxel((IMP::algebra::ExtendedGridIndexD< 3 > const &)*arg2,(double const &)*arg3);
                ~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/cccTsakr.out file, please attach this to your bugreport.


Expected results:
Compilation succeeds.

Additional info:
As requested by g++, preprocessed source is attached.
Comment 1 Marek Polacek 2016-06-23 11:16:54 UTC 
This seems to be fixed on the trunk, but I'm trying to bisect this to a particular commit.  Unfortunately, the source code is humongous, so it's taking time.
Comment 2 Marek Polacek 2016-06-23 12:49:49 UTC 
This was fixed in r236430.
Comment 3 Fedora Update System 2016-06-24 18:56:15 UTC 
gcc-6.1.1-3.fc24 gcc-python-plugin-0.15-6.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-6db2423f35
Comment 4 Ben Webb 2016-06-24 19:38:42 UTC 
Thanks for getting to this so quickly, and pinning it down to a precise commit (sorry, SWIG has a tendency to generate enormous wrapper files for C++ code). The updated package works fine for me, compiling our code without issues.
Comment 5 Fedora Update System 2016-06-26 00:27:07 UTC 
gcc-6.1.1-3.fc24, gcc-python-plugin-0.15-6.fc24 has been pushed to the Fedora 24 testing repository. If problems still persist, please make note of it in this bug report.
