Help with this.

I'm starting to do win32 exploits and shellcoding, but I hit a problem when a supposed vulnerable program won't segfault when run on my machine.

I wrote it in dev-cpp's ide with console mode template. When run on command line on windows 2000 professional;

[ the A's were on the commandline, email client put it below]

C:\sources\vuln1

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
                       [pretty sure it was sufficient]

C:\sources\

When finnished running, there is nothing; no output, no errors, no pop-up boxes. Tried it as a regular user and as administrator.

However, when run with the same arguments on windows millenium, a standard pop-up comes up stating that vuln1 has caused an error in <unknown> module and will be shutdown. No detail button on the dialog though.

vuln1.c

int main(int argc, char *argv[])
{
char buffer[30];

if(argc > 1)
{
strcpy(buffer, argv[1]);
}

return(0);
}

Maybe dev-cpp changes the way strcpy functions? Or win2k works way diferent than I expect? I've done exploits with linux and bsd, and to my knowledge this should be the same. Any help would be greatly appreciated.
