python print c.type == gdb.parse_and_eval('d').type
./python/py-type.c:902: internal-error: VEC_type_equality_entry_d_quick_push: Assertion `quick_push' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n) FAIL: gdb.python/py-type.exp: python print c.type == gdb.parse_and_eval('d').type (GDB internal error)

On Fedora 13 x86_64 for example with `./configure; make'.

It PASSes with the fix.  Tested only gdb.python/py-type.exp on
x86_64-fedora14snapshot-linux-gnu.

OK to check-in?


Thanks,
