[PATCH] Add a testcase similar to linuxthreads one to NPTL as well

[Jakub Jelinek <jakub@redhat.com>]

Hi!

NPTL passes this test already, but adding it to the testsuite certainly
doesn't hurt.

2003-12-17  Jakub Jelinek  <jakub@redhat.com>

	* Makefile (tests): Add tst-stack3.  Depend on $(objpfx)tst-stack3-mem.
	(generated): Add tst-stack3.mtrace and tst-stack3-mem.
	(tst-stack3-ENV): Set.
	($(objpfx)tst-stack3-mem): New.
	* tst-stack3.c: New test.
