Using gcc 4.3, I did not see this error.   What compiler or compiler
options did you use to get this?

I assume it means the stack space was exhausted and a casual glance at
the code did not yield anything obvious like a large array on the stack
or anything.  It is conceivable that there is an inline function that is
the source of the problem, but I would like to be able to duplicate it.

Thanks,
Jason.
