Re: [Boost-users] boost::bind triggers seg fault if compiled with gccoptimizations

Hi Peter!

bind_test passes for my compiler. I actually cannot sent you a senseful
backtrace, since the compilation in debugging mode always yields a
executable which works as it should (even though optimizations are on).
Only compiling in release mode with -Ox x>0 yields a crashing
executable. Seems like a gcc bug to me, but I thought some Problems like
this are known. Attached is the affected code.

Greetings,

Sebastian Weber
