Thanks for fixing so fast!
This gives best motivation for further bug reports.

Could be a good idea to incorporate regexp-test.fs into BUILD-FROM-SCRATCH build chain.

Thanks for reporting.  The number of items on the control flow stack changed, and the code was assuming a fixed number (3).  Fixed in git head.
