any tool for core analysis on HP-UX?

Hi,

I just wanted to know is there any tool avaliable for core analysis on hp-ux. I have heard about q4 utility. But I think it is used for analysis of system crash dump and not for core dump produced by a user process.

gdb doesn't give much information unless the binary is debug-build.

Any pointers would help.

Thanks in advance,
