Comment (by cypherpunks):

 Stack trace unreadable if FPO enabled in general or used optimization
 options (then FPO applied selectively by compiler depends function's code)
 for x86 platform. It's not problem for x86_64 because GCC generates unwind
 tables there by default.
 If to enable unwind tables unconditionally by "-fasynchronous-unwind-
 tables" then stack trace readable with any optimizations.
