            Bug ID: 30630
           Summary: remote.c:8352: internal-error: wait: Assertion
                    `!async_event_handler_marked
                    (rs->remote_async_inferior_event_token)' failed.
           Product: gdb
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org
          Reporter: christian.prochaska@genode-labs.com
  Target Milestone: ---

I got this error while working on a custom GDB stub which sends two initial
stop replies and could reproduce it with gdbserver with the following test:

#include <pthread.h>
#include <stdio.h>
#include <unistd.h>

void *thread_func(void *)
{
        sleep(1000);
}

int main()
{
        printf("pid: %u\n", getpid());
        pthread_t t;
        pthread_create(&t, 0, thread_func, 0);
        pthread_join(t, 0);
        return 0;
}
