Re: gprof 2.14 glitches w/ powerpc elf binaries

Actually what is probably happening is that gprof is trying to associate 
an address in the executable with a function name, and it is this 
association which is going wrong.  So for example the reference to 
Letext is probably actually an address somewhere near the end of the 
.text section.

This problem may be a result of the debug format that you are using, or 
it may be a binutils problem.  You could try upgrading to the 2.15 
binutils release and if that does not work then you could try the 
current mainline sources in the CVS repository.  Failing that if you can 
create a small, reproducible test case we can try to look into it ourselves.

Cheers
