Well, that confirms things. 7.4.2 includes a repeated call to dup(0) to get
an estimate for the max number of fds, whilst 7.4.1 does not.

Code like that below should not SEGV, IMNSHO. Want me to push this over to
the cygwin list?


#include <errno.h>

int main(void)
{
	int i;
	for (i = 0; ; i++)
	{
		printf("i = %d\n",i);
		if (dup(0) < 0)
		{
			printf("dup failed\n");
			return -1;
		}
	}
	return 0;
}

Congrats.
