Hi All,
This is a false positive, obviously. We do our best to filter out flaky tests, but in this case "gdb.threads/staticthreads.exp: up 10" PASSed twice in the previous run, and then FAILed twice in the next run. Sneaky!
Re. the FAIL, the testcase expects to be " in main .*" after "up 10", but ends up in pthread_join() instead: === up 10 #4 0x0001b864 in pthread_join () (gdb) FAIL: gdb.threads/staticthreads.exp: up 10 === See [1] for details.

Hi Thiago,
Would you please investigate whether ending up in pthread_join() is expected/reasonable for 32-bit ARM? In other words, whether we have a GDB bug exposed by staticthreads.exp or the testcase needs to be generalized a bit.
Thank you,
