The test added by this commit catches it: /home/pedro/gdb/mygit/build/../src/gdb/linux-nat.c:3198: internal-error: linux_nat_filter_event: Assertion `lp->resumed' failed. A problem internal to GDB has been detected, further debugging may prove unreliable. Quit this debugging session? (y or n) FAIL: gdb.threads/non-leader-exit-process.exp: program exits normally (GDB internal error) The fix is just to remove the assertion. With that out of the way, neither GDB not GDBserver handle this perfectly though, so I'm adding a KFAIL: (gdb) continue Continuing. [Thread 0x7ffff7fc0700 (LWP 15350) exited] No unwaited-for children left. Couldn't get registers: No such process. (gdb) KFAIL: gdb.threads/non-ldr-exit.exp: program exits normally (PRMS: gdb/18717) gdb/ChangeLog: 2015-07-24 Pedro Alves <palves@redhat.com> PR gdb/18717 * linux-nat.c (linux_nat_filter_event): Don't assert that the lwp is resumed, and extend the debug log. gdb/testsuite/ChangeLog: 2015-07-24 Pedro Alves <palves@redhat.com> PR gdb/18717 * gdb.threads/non-ldr-exit.c: New file. * gdb.threads/non-ldr-exit.exp: New file. -- You are receiving this mail because: You are on the CC list for the bug.
