Hi,
I reported what I thought was a bug in glibc:
http://bugzilla.redhat.com/365111
in which I tried to make gdb simulate a mmap64 failure.
However, using "ret (void*)-1" appears not to do what I expected.
In comment #6, Ulrich showed that setting an arch-specific register
did what I wanted:
http://bugzilla.redhat.com/365111#c6
Is there a way to make gdb do that portably?
Jim
