| Summary | 0000190: solver type constraint_store declaration has trouble unifying imported types | ||||||||
| Description | If a solver type constraint_store declares a mutable of an imported type (say list), it fails trying to unify the unqualified type name with the qualified version (e.g. list(int) with list.list(int)). | ||||||||
| Additional Information | A workaround is to prefix the type name in the mutable declaration. The bug does not occur in normal mutable declarations. | ||||||||

The problem here is that module qualification skips the constraint_store attribute. |

More info: this seems also to occur with locally defined types and equivalence types (equivalences aren't checked). |

I've committed the a fix for the first problem. The second problem is due to equivalence types in the constraint_store attribute not being expanded; I'm presently testing a fix for that. |

A fix for the problem with equivalence type expansion in constriant_store atttributes has been committed as well. |
