Interesting, but would that affect the rate at which userland code consumes stack space? Since posting, I've verified that it still fails at STACK_MIN_SIZE = 48K, which is 300% of the setting that had worked up through mid-December. So *something* has gone pretty seriously wacko, but it's hard to tell what. I guess I shall have to request buildroot access and start poking at it with a debugger ... regards, tom lane -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
