Actually HP-UX has its own great forum on ITRC and some HP staff members are very helpful. I just took a look at the same topic you are asking and here are some results. For example the similar problem was caused actually by a bad input parameter. I strongly advise you first to read answers to similar question and if necessary to post your question there.

By the way it is likely that you will be asked to post results of these gdb commands:

(gdb) bt
(gdb) info reg
(gdb) disas $pc-16*8 $pc+16*4
