Comment(by selinger):
Yes, the type error is about right. Were you able to reproduce this in
7.2.2? The bug seems to be unstable, i.e., small changes in the source
code make it go away. So it may be okay in HEAD because whatever the
problem was has been fixed (which would be great), or because HEAD
compiles some things in a slightly different order (in which case the bug
may still be present, and may just not manifest with this particular
example).
