Description of problem: If you forget to wrap some function of the dual-built (_local/_generic) sources by UNW_OBJ() the code has hard to reproduce crashes. Version-Release number of selected component (if applicable): HEAD How reproducible: Always. Steps to Reproduce: 1. Apply the attached patch. 2. make check Actual results: -PASS: test-static-link +/bin/sh: line 4: 17625 Segmentation fault ${dir}$tst +FAIL: test-static-link -PASS: Gtest-bt +/bin/sh: line 4: 17633 Segmentation fault ${dir}$tst +FAIL: Gtest-bt -5 of 24 tests failed +7 of 24 tests failed Expected results: Compilation error or some other sanity check. Additional info: $ nm `find -name "*.o"`|perl -ne 'chomp;/:$/?$p=$_:print "$p$_\n"'|grep ' T dwarf_step' ./src/dwarf/Gstep.o:00000000000003a3 T dwarf_step ./src/dwarf/Lstep.o:0000000000000245 T dwarf_step The problem is the linker will silently link only with the first function found and it will ignore the remaining global definitions of the functions. There should be implemented into the libunwind build framework a sanity check for duplicite symbols during linking. This is not easy to debug as it is all heavily macroized and built from the same source files (debugging gets hopefully more manageable now with the recent F9 GDB featuring the multi-PC source lines functionality).

Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '9'. 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 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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. Thank you for reporting this bug and we are sorry it could not be fixed.
