When I try to run gdb, it fails to even create the child process. For example, trying gdb on /bin/cat: ------------------------ % gdb -nx /bin/cat Reading symbol data from /bin/cat... (no debugging symbols found)...done. Reading symbol data from /usr/shlib/libsys_s.B.shlib...done. (gdb) b abort Breakpoint 1 at 0x505358a (gdb) run Starting program: /bin/cat Program generated(1): Memory access exception on address 0x7d6f8 (invalid address).
