Thanks! I'll fix this. Getting up to speed on the cpp-ness of it!

PS2, Line 195:
No use case in particular for a NULL tdesc, though i tend to think
having the check here prevents having to add such a check elsewhere.
We don't want gdbserver to die when we see a NULL tdesc for example.
Unless a NULL tdesc is a major error we don't want to allow. Then i
agree an assert would be good. Thoughts?
