After you hit control C, you could put a breakpoint somewhere in your
stack trace.  Or you could put a breakpoint in malloc.

That seems like it would work.

Then my solution above may not work either?

Possibly.  Is Dutta's process making progress?
Try continuing and hitting Control C then trace.

You can use "info func foo.*bar" to look up regular expressions.

[bani] Yes the shared lib has been loaded (i know because of some traces).

You can also know by using "info shared".
And can use "catch load" to stop when loaded.
