Problem when restarting program under gdb 7.2

I now have gdb 7.2 running mostly fine, but it seems to crash rather
regularly if I restart a program already being debugged under gdb. This
doesn't happen with the default Xcode gdb.

For example:

mortgage:miscprog stanton$ gcc -g -DMAIN amput.c -o amput
mortgage:miscprog stanton$ fsf-gdb amput
