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

Here is the stack trace (CFLAGS are -g -gdb)
