this pointer getting screwed

[Steven Wong]

hi,

I've got a pthreaded app, which seg faults. Taking a look at the
stack in gdb
I notice the "this" pointer gets nulled in the stackframe where the
seg fault occurs. Say its in an object, this really messes up things,
since trying to
access member variables will cause some big problems.

What could cause the this pointer to get screwed up like that?

TIA

You probably invoked a member function using a null-pointer. Check the
code that calls your function.
