Comment(by simonmar):

 There's a Core Lint error after the first simplification pass; I've
 attached a log from `-dverbose-core2core -dcore-lint` in case this helps
 Simon track down the problem (he was having trouble repro'ing because
 regex-posix doesn't build on Windows, which is a different problem).
