I think the obvious thing to check is whether it's stuck in a loop
trying to open a temporary file.  There are a couple of loops to
check on: fmt_tempname (the current function), and LYOpenTemp (the
caller of fmt_tempname).

If you type "finish", gdb will try to finish the current function.
If it's stuck in a loop, it won't come back - and you can control/C
back to gdb's prompt.  Doing that twice would normally get back to
HTCompressed.

Perhaps there's some problem making the temporary files not created properly.
That would be relatively easy to diagnose, by looking at the local variables
of the function that's stuck.
