Description of problem:

g++ crashes when compiling with -fprofile-use.


Version-Release number of selected component (if applicable):

gcc-4.7.0-5.fc17.x86_64


How reproducible:

Always

Steps to Reproduce:
1. Build with -fprofile-generate
2. Run program to generate profiling data
3. Build with -fprofile-use
  
Actual results:

g++ -o bin/src/lib/parser.o -c -MMD -MP -fprofile-use -std=c++11 -O3 -W -Wall -Wextra -Wnon-virtual-dtor -pedantic -pipe -isystem vendors/scope -Iinclude src/lib/parser.cpp
src/lib/parser.cpp: In member function ‘void std::_Sp_counted_ptr<_Ptr, _Lp>::_M_dispose() [with _Ptr = CachingICUEncoder*; __gnu_cxx::_Lock_policy _Lp = (__gnu_cxx::_Lock_policy)2u]’:
src/lib/parser.cpp:83:1: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccjvdye1.out file, please attach this to your bugreport.

Expected results:

Successful compilation.

Additional info:

My program compiles without incident without -fprofile-use. The crash happens on the same file every time. If I comment out line 83, I can successfully compile with -fprofile-use. I can't provide the complete program, unfortunately, but I'd be happy to do whatever else is needed in order to solve this.

Comment 1 Fedora End Of Life 2013-07-03 22:49:46 UTC 
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. 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bug reports from releases that are no longer maintained.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 '17'.

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 17'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 17 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 17'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.
Comment 2 Fedora End Of Life 2013-08-01 00:59:33 UTC 
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 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.
