This explains a question I was getting ready to pose. Apparantly, gcc adds stack probing whenever allocating large (>4k) space on the stack. I thought that this would extend the stack. I guess it does assist in doing so by increments of sizecommit, but will not extend past sizereserve. So, I need to set the sizereserve to something nice and large. As mentioned, this is done with the -stack option to ld and can be made a default option when linking with gcc. Thanks for the info. - For help on using this list, send a message to "gnu-win32-request AT cygnus DOT com" with one line of text: "help".
