Hi Andrew,
thanks for replying.  I'm not sure it causes any incompatibility.
I'm pretty sure you don't need to recompile gprof after this patch;
gprof compiled before the patch works fine with user executables
compiled with a patched glibc.  The patch doesn't affect the format
of data on disk.

Can you be more precise about how this patch causes an incompatibility?
