So you are really at it, that's cool! :)
Not that I can use your new test-case, as it now works like this:

Program received signal SIGALRM, Alarm clock.

2: /x $rcx = 0x7ffff7d0cd94
(gdb) 

And falls inside the gdb prompt, with "PASSED" already written...
But I guess I'll just try my own test-case on an already fixed
gdb some time later. :)
