Running make without arguments produces a segfault when /dev/pts isn't mounted. This makes building in a chroot jail a bit of a pain if you don't mount /dev/pts. Sometimes I don't even bother mounting /dev/ and this only happens in 4.1 at ~ # make make: *** No targets specified and no makefile found. Stop. at ~ # umount /dev/pts/ at ~ # make Segmentation fault at ~ # Here is the stack trace (CFLAGS are -g -gdb) (gdb) bt #0 0x00007ffff769ab7a in strlen () from /lib64/libc.so.6 #1 0x00007ffff769a8be in strdup () from /lib64/libc.so.6 #2 0x000000000041e82b in xstrdup (ptr=0x0) at misc.c:259 #3 0x000000000042c922 in define_variable_in_set (name=0x434a53 "MAKE_TERMOUT", length=12, value=0x0, origin=o_default, recursive=0, set=0x440580 <global_variable_set>, flocp=0x0) at variable.c:243 #4 0x0000000000419cad in main (argc=1, argv=0x7fffffffe048, envp=0x7fffffffe058) at main.c:1404 Reproducible: Always Steps to Reproduce: 1. unmount /dev/pts 2. run make 3.
