Yes Simon, in fact with ML, taskgated isn't launched with option -p (manual=
 said: old (Tiger) convention that a process with a primary effective group=
 of procmod or procview is allowed to get task ports. Without this option, =
this legacy mode is not supported.)
As you said for Lion, and in my case with SL, taksgated was launched with o=
ption -p.
Thus with ML even gdb has setgid procmod group, it is blocked by taskgated.

Fortunately the -s option of taksgated (active with both SL and ML) let us =
codesign gdb to proceed.
Well, GNAT gdb is already signed:
Authority=3Dgnat_debugger
Signed Time=3D14 mai 2012 16:25:55
It seems that taksgated need a local system signature thus we have to follo=
w instructions on http://sourceware.org/gdb/wiki/BuildingOnDarwin.
And we must force it with -f option:
$ codesign -fs gnat_gdb gdb
gdb: replacing existing signature
It is now ok.

Don't forgot to add option '-largs -Wl,-no_pie' if you want to get good lin=
e numbers.

HTH, Pascal.
