Hi g sobers, > Would appreciate assistance with addressing the situation. f is a dangling pointer. f1 just happens to point to the recently closed buffer that f used to point to. I would not rely on that behavior. Not only is it non-portable, it may not work that way reliably even on the same platform. It's a bug in the code. Not in GCC, nor on Cygwin. HTH, --Eljay
