uname -a:
Linux lit3n4014e 2.6.22.18-0.2-bigsmp #1 SMP 2008-06-09 13:53:20 +0200 i686
i686 i386 GNU/Linux
OS is SuSE 10.3 IA32 on a Core2 Duo machine.
See attachments for g++ -dumpspecs, pre-processed source that demonstrates the
problem, assembly generated by g++ and (on the chance that it's useful)
assembly generated by the latest version of Intel's compiler.
There's a segfault on what gdb thinks is the first "real" line of
PerformanceStatistics<enabled_domain>::Scope<enabled_domain::function_c>::~Scope().
The segfault also occurs in the same place if:
1) I replace lCycles = mCounter.GetElapsedTime() with lCycles = 0
2) I leave the line lCycles = mCounter.GetElapsedTime() untouched and instead
comment out the rest of the if statement
The problem only occurs when -fPIC and -finline are both enabled. I can compile
with -O3 -fno-inline and the problem goes away or I can compile with -O0
-finline and the problem appears.

--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I can't reproduce the results in GCC 4.9 or above (I have not really tried
anything before either).
