This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 WONTFIX if it remains open with a Fedora 'version' of '18'. 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 prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 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 to Fedora 18's end of life. 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. This is still an issue with dwarves-1.10-4.fc20.x86_64 and gcc-c++-4.8.2-7.fc20.x86_64: g++ -g -std=gnu++11 test.cc pahole ./a.out die__process_unit: DW_TAG_rvalue_reference_type (0x42) @ <0x1e7> not handled! This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22 Initial support upstream at: https://git.kernel.org/cgit/devel/pahole/pahole.git/commit/?id=9df42c68265d1750eecbf386fca1c47d428ac207 Please take a look, more work needs to be done. Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Created attachment 747460 [details] simple class tester with abstract base class Description of problem: Take the attached sources, and compile for C++11 like: %g++ -g -std=gnu++11 test.cc %pahole ./a.out die__process_unit: DW_TAG_rvalue_reference_type (0x42) @ <0x1cf> not handled! Then do the same thing for C++98: %g++ -g sa-04-C.cc %pahole ./a.out Fine. So, there is some weird C++11 DWARF construct that pahole is choking on. This is only with gcc-4.8 and above. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
