It passes cleanly. And I confirmed that that test idea triggers the suspend count assertion I suspected: Child exited with status 0 /home/pedro/gdb/mygit/build/../src/gdb/gdbserver/linux-low.c:2619: A problem internal to GDBserver has been detected. unsuspend_one_lwp: Assertion `lwp->suspended >= 0' failed. [Inferior 1 (process 32473) exited with code 01] (gdb) I'll convert that to a proper test. Thanks, Pedro Alves
