>Description:
On a kernel compiled with DEBUG and LOCKDEBUG, running gdb(1) on any
trivial program locks up the whole system.
>How-To-Repeat:
As any user on a kernel with DEBUG & LOCKDEBUG:
```
$ echo 'int main(void) { return 0; }' > t.c
$ cc -o t t.c
$ gdb t
(gdb) run
```
System locks up completely. Must power off to recover.
>Fix:
No idea.
