Summary0000021: equivalences for solver types lead to badly typed initialisation predicates
DescriptionThe attached code fragment exhibits a bug with solver types and
equivalence types that causes the compiler to report that an
initialisation predicate is badly typed. (The fragment compiles
without error if the equivalence type definition is commented out.)

(At a cursory glance, it looks like expansion of equivalence types is
not happening somewhere.)
TagsNo tags attached.

Support for automatic initialisation of solver types has been removed so, in a sense, this bug
can no longer occur.

The actual bug has also been fixed in the developer-only support for solver initialisation.

See the log message of r1.195 of compiler/unify_proc.m for details.
