Application core dumps

Rhett Butler — Mon, 16 Jan 2006 11:08:42 GMT

I am trying to install a C++ application into HP-UX 11.11

The GUI opens and runs properly. Once i close it and reopen the GUI the application dumps core.

Please find the GDB Stack trace

I've turned on my psychic powers and I will now debug your (unnamed) application without the source code. I'm getting ... Oracle? ... version 10ish? ... possibly using malloc to allocate memory and delete to free it? ... crystal ball is clouding over ...

I don't think anyone is going to get any points here, but Stephen deserves to get 10!

As Arun said, run tusc.

Run "file" on the core file produced and note which signal the process terminated on and then take that information back to the application vendor and ask them if it's a known problem. They are likely to have seen this before if it's strictly a software and not a config problem.
