Fails also with the same error on julia 1.1. I am pretty sure this used to work.

@thofma The problem arises because of a bug in gap-system/gap#3669, in the GAP master branch.

[thofma]

Thanks. Any way to work around this? Is the GAP version in GAP.jl fixed or does it pull in the latest master branch of GAP?

[fingolfin]

I'll take care of this shortly. Thomas made me aware if this before, but I didn't get to it yesterday

[fingolfin]

The problem is a missing change on the GAP.jl side, plus a lack of proper integration testing in the GAP CI tests, which do have some minimal tests for the Julia integration, but do not test against GAP.jl yet. I'll look into that, too
