That was intended, I find the patch useless/buggy without it.

"frame" worked fine but I have found for example this case does not:

(gdb) frame
#0  0x00007ffff637d7d0 in __poll_nocancel () at /usr/src/debug/glibc-2.16-75f0d304/sysdeps/unix/syscall-template.S:81
81	T_PSEUDO (SYSCALL_SYMBOL, SYSCALL_NAME, SYSCALL_NARGS)
(gdb) info line *$pc
Line 81 of "../sysdeps/unix/syscall-template.S" starts at address 0x7ffff637d7c0 <poll> and ends at 0x7ffff637d808 <poll+72>.

Not with me.

I was thinking about such change before but I have left it according to the
original submitters proposal which may match best where the users would search
for it.  OTOH when I check now the former thread it even did not come as the
original submitters proposal so it could be changed.
