Hi all,
I am trying to compile some X and Motif applications
with cyg-gcc b19
My application fails with a seg violation.
However, the stack trace core file which is left is
just a text file of the stack frame with addresses in
hex.
gdb cannot read this in. My problem is that I do not know 
how to relate these addresses back to actual function
calls.

As well, when I run the application under gdb, when I hit
the seg violation, I cannot do a where - gdb says
that it cannot access memory at xxxxxx.

As this error seems to be hidden ~ 15 levels into a large loop
I have not even been able to get near to determining where
the problem is.

Is it possible to either
1. get a core file that gdb can under stand
2. set a break point on some system call which is 
	invoked when the seg violation occurs
3. set strace to a useful value which will help

Any help will be greatly appreciated

Cheers
Anthony
