Just a heads up, in case somebody else is running in the same problem:

Gdb on both hpux10.20 and hpux11.00 hangs after the 'run' command is
issued.

It seems that the problem is due to a broken vfork() implementation.
(Jeff, correct me if I am wrong here)
If fork() is used to start the inferior, all works fine.

A possible workaround, courtesy of Jeff Law, is to define vfork() to
fork().

Something like this works (analogous for 11.00):
