internal compiler error: in expand_expr_real_2, at expr.c:8701

Error is reproducible in compiler explorer with both gcc 10.2 and gcc trunk.
See attached URL for a minimal reproduction scenario.

The error seems to occur when trying to use the stored pointer to member in the
lambda.

I tried adding the suggested compiler flags but this did not influence the
result.

The code compiles fine in clang 11.
