PR13901


Tristan,
   Have you noticed that recent FSF gdb releases including 7.4 have been
non-functional when built targeting i386-apple-darwin? The run-time failures
have changed between 7.2 and 7.4. Currently the failure is exhibited as
errors of the form...

(gdb) break main
Breakpoint 1 at 0xd80: file himenoBMTxpa.c, line 71.
(gdb) r
Starting program: /Users/howarth/a.out 
darwin_set_sstep: unknown flavour: 4
Error calling thread_get_state for GP registers for thread 0x8451lxwarning:
Mach error at "i386-darwin-nat.c:118" in function
"i386_darwin_fetch_inferior_registers": (os/kern) invalid argument (0x4)

Is this something that is trivial to fix? It would be nice if both MacPorts
and fink could have a functional i386 build of FSF gdb. In fink, we currently
have gdb restricted to x86_64 fink (although the x86_64-apple-darwin build
can debug i386 binaries fine). MacPorts has left their gdb pacakge at 7.1
(which I guess is that last version that worked for both i386-apple-darwin
and x86_64-apple-darwin. Thanks in advance for any clarifications.
           Jack
