Testing that packages still compile

Dear all,

I am part of the OCaml development team. As you may know, OCaml has a
package manager a bit similar to cabal whose name is opam.

One of my colleagues spends quite a lot of time trying to make sure that
packages still compile with a new version of the compiler, when we
release it. When a package does not compile any longer, it seems it is a
highly non-trivial task to figure out what exactly is broken: is it the
package itself which has been broken by a change in the compiler, or is
it one of its dependencies.

I am assuming the same kind of problems occur with Haskell and am
wondering how they are handle.

Has there been something published on this kind of problem?

Any pointer, comment or contact appreciated.

Best wishes,
