Greetings,
I saw the FAQ about bad memory allocations and it looks I have run into
this situation. What I'd like to know is what tools should I use next to
try and understand why this area of code is misbehaving. It could be
machine specific, I don't see this error on one hundred other systems,
and my memtest86 run passed. Thank you for your suggestions.
Jed
