This is a case of semantically equivalent regex not being computationally equivalent. The issue also relates to how negative character classes (e.g. `[^abc]`) are treated. In the end I had to replace something of the form `(A | B)*` with `A* (BA*)*` to avoid grinding the regex engine to a halt. Issue #150.
