New description:

 Bad news.  On Windows, every binary built with GHC HEAD (as of today) seg-
 faults.  Even
 {{{
 main = print “Hello”
 }}}
 Thus
 {{{
 /cygdrive/c/tmp$ c:/code/HEAD/inplace/bin/ghc-stage1 Hello.hs
 [1 of 1] Compiling Main             ( Hello.hs, Hello.o )
 Linking Hello.exe ...
 /cygdrive/c/tmp$ ./Hello
 Segmentation fault/access violation in generated code
 }}}
 (And of course including the stage-2 compiler.)
 This started happening sometime in the last day or two; I don’t know
 exactly when.
 This is with a fresh tree, downloaded from the git repo, with config
 settings for validation.

 Might someone look at this?  It’s pretty serious!

 Simon
