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.
