Subject: [patch] Fix attaching to Linux stopped processes

Hi,

sleep 1h& pid=$!; kill -STOP $pid; gdb sleep $pid
	->
Attaching to program: /bin/sleep, process 20768
../../gdb/linux-nat.c:1057: internal-error: linux_nat_attach: Assertion `pid == GET_PID (inferior_ptid) && WIFSTOPPED (status) && WSTOPSIG (status) == SIGSTOP' failed.


Testsuite not affected.

Not tested if the patch is properly utilized on older (<=2.4) Linux kernels.

	* gdb/linux-nat.c (linux_nat_attach): Handle already stopped
	processes.

	* gdb.base/attachstop.exp, gdb.base/attachstop.c: New files,
	test attaching to already stopped processes.



Regards,
Jan
