Hi

Thanks a lot to Philippe for fixing the previous bug so quickly! Never got
fixed a bug as fast by WindRIver despite having paid quite a lot of money
for it!

Now my testsuite passes almost all tests but crashes, when it spawns
twice a task with the same name. E.g. I get the following output:
> testTask done t1 0x901a0f4 t2 0x901a2b4
> Xenomai/SOLO: duplicate task name: Test
> assert passed at task1 line 24
> assert passed at task1 line 24
> assert passed at task1 line 26
> assert passed at task1 line 26
>
> Command terminated by signal 11

Attached my simple test case.

Best regards
