Runtime error in bimaps_with_arg in generics1

The ABC optimiser in https://gitlab.science.ru.nl/clean-and-itasks/abc-interpreter fails to build with the latest (itask) compiler due to a runtime error in generics1:

Run time error, rule 'bimaps_with_arg;347' in module 'generics1' does not match

I have not tried the master compiler.

This is the source of just the optimiser for your convenience: abcopt.tar.gz
