New description:

 When compiling with -v with a compiler built today, I see:
 {{{
 [X of Y] Compiling Foo.Bar       ( /home/<user>/Foo/Bar.hs,
 /home/<user>/Foo/Bar.o )
 *** Parser:
 *** Renamer/typechecker:
 }}}
 There is no progress. It ran about 10 minutes before I killed it. Foo.Bar
 is the last module in the compilation, so it should be just before the
 link step.

Comment (by simonpj):

 Ron,

 You are wonderful at finding bugs in GHC -- thank you.

 But we absolutely can't fix them without a way to reproduce them.

 It's the same for #1640 which I can't make progress on either, for the
 same reason.

 Please help us by giving us a way to reproduce your bug(s)

 Simon
