I executed an internal script with --vec

TBD

After failing I started it with gdb and saw it running.... the next try with gdb gave this bt:

I strongly suspect this is a duplicate of #881. You could try to run this again with the changes from #882. This is not merged yet as I only fixed the problem of crashing, and have not yet fixed the root cause.
