To make constant strings read-only they are put into the code segment. During ordinary runs, the code segmant will be read-only on Win/32. OTOH gdb needs to be able to change the code to add breakpoints, so under a debugger the code segment will be writable to allow this. so long, benny ====================================== Benjamin Riefenstahl (benny@crocodial.de) Crocodial Communications EntwicklungsGmbH Ruhrstr. 61, D-22761 Hamburg, Germany - For help on using this list (especially unsubscribing), send a message to "gnu-win32-request@cygnus.com" with one line of text: "help".
