Analysing core files

[mehaboob]

Hi,

I have a core file generated by an application on Tru64 machine.I have
some tool which generates the output as below.But from here am not sure

how to proceed further or what to look for....Any help would be deeply
appreciated.

And also am not sure what is meant by signal ILL?

Your program isn't feeling very well; give it some medicine and it'll
get better.

As the output says, that's a "stack trace". Basically, it shows the nesting
of function calls that has led to the point in the code where something (a
crash, or your tool, perhaps) told the software to stop.

Since we don't know what you're trying to do or find, we can't tell you what
to look for.

Your best bet would be to read the documentation for the tool, I would
guess. Or for your operating system, perhaps.

(And you might find info about "signal ILL" by doing a Google search.)
