Gary stumbled on this: (gdb) PASS: gdb.threads/thread-specific-bp.exp: all-stop: continue to end info threads Id Target Id Frame * 1 Thread 0x7ffff7fdb700 (LWP 13717) "thread-specific" end () at /home/gary/work/archer/startswith/src/gdb/testsuite/gdb.threads/thread-specific-bp.c:29 (gdb) FAIL: gdb.threads/thread-specific-bp.exp: all-stop: thread start is gone info breakpoint The problem is that "...archer/startswith/src..." has a "start" in it, which matches the too-lax regex in the test. Rather than tweaking the regex, we can just remove the whole "info threads", like we removed similar ones in other files -- GDB nowadays does this implicitly already, so things should work without it. Thus removing this even improves testing here a bit. gdb/testsuite/ChangeLog: 2015-03-04 Pedro Alves <palves@redhat.com> * gdb.threads/thread-specific-bp.exp: Delete "info threads" test.
