Hello all,
I tried to reproduce this issue.
Unfortunately I never get the "(SEGFAULT)" output for all tests,
just "(Failed)" for most. But some do really segfault in my amd64 VM.
I think the segfaults are caused by the line "delete component;", that
invalidates the iterator by removing its element from the components vector.
For some reason the iterator contains still the previous pointer
and therefore we try to delete the same pointer twice.
Attached patch tries to change the loop assuming that the
deleted element will always be removed inside the delete operation.
With that patch I do not get any segfault, but still tests
fail for some reason.
Kind regards,
Bernhard
