Comment (by edmund):

 So the stage1 compiler builds a stage2 compiler which fails when building
 anything at all. But the stage1 compiler builds a hello.hs that works
 (comment 10, above). Would it be possible to run the testsuite on the
 stage1 compiler, with various optimisation options, to get an idea of what
 the stage1 compiler can and cannot do? That might lead to a simpler test
 case than GHC itself, or there might be some interesting pattern in the
 failures. Just a suggestion.
