I got this response from Robert, the root cause sounds plausible (amd64
vs i386 not preserving ecx).
Any chance of an MFC? I see one is pending in the PR.
If I can test and verify the change I could MFC.

Hi,
GCC 4 gprof profiling for i386 has been broken on FreeBSD for quite a while.
See PR bin/119709. It appears that the fix has been MFC'd recently:
$FreeBSD: src/sys/i386/include/profile.h,v 1.42.2.1 2008/10/13 12:45:18 kib
Exp $
(I've been successfully using gprof by patching using the code in the PR but
haven't rebuilt my system with the above change)
Is there a similar problem for AMD64?
Cheers,
Rob Jenssen
