Commit 338b5cb98e changed a call in
handle_inst_var_subs_2, essentially from
Recurse(InstA, SubInstB)
to
Recurse(InstA, abstractly_unify_inst(InstA, SubInstB))
Unfortunately, it results in infinite recursion on some cases.
compiler/inst_match.m:
Revert the change to handle_inst_var_subs_2.
tests/EXPECT_FAIL_TESTS.all_grades:
Expect constrained_poly_insts2 to fail now.
tests/invalid/constrained_poly_insts3.err_exp:
tests/invalid/constrained_poly_insts3.m:
tests/invalid/constrained_poly_insts4.err_exp:
tests/invalid/constrained_poly_insts4.m:
Add test cases.
