Does this one happen with current mainline?  Could you do the same test, but
with "set debug infrun 1", so we could see gdb's internal run control debug

Thanks.  There's no internal-error in mainline then.  We instead see the same
^error as PR14629.

Not many active gdb people have HPUX access these days.  You may need
to debug this yourself.

:-)

I've opened PR14653 to track the ttrace error issue.

Closing this as the original bug is fixed.
