Hi. If the inferior exits gdb will now crash in the call to inferior_thread:

if ((terminate_bp != NULL) &&
== terminate_bp->loc->address))

Good catch, and thanks for taking the time to fix this.

I'll submit the attached patch upstream as while gdb doesn't crash,
the error message it currently prints is confusing.
Shall I check it into archer or the exception-rewind branch?

Personally I'd check it into the exception-rewind-branch. Archer and that branch are as yet two separate branches. As this fixes a crashing bug in that branch, and fixes a confusing message upstream. Can twiddle the bits later to make the "eventual" merge of archer-rewind happy.
