[Bug c/18929] New: Profiling optimized code causes segfaults on ARM due to missing frames

["opensource at artnaseef dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When compiling with the arm-linux compiler with optimization enabled, the 
compiler removes frame pointers from functions even when they are profiled.  
This leads to a segmentation fault with the glibc version of mcount when it 
attempts to determine the caller of a function from the current stack because 
mcount assumes the frame pointer is there.

It seems that optimized functions, on this platform, should not drop their frame 
pointers when profiling is enabled.
