With this patch:
hunk ./compiler/parser/Lexer.x 535

+#else
hunk ./compiler/parser/Lexer.x 539
+#endif
something goes wrong. The first sign, when validating, is that timeout is broken:
timeout: internal error: stg_ap_v_ret
(GHC version 6.9.20080902 for x86_64_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
If you use the python timeout program instead then you find a few tests fail, e.g.:
testsuite/tests/ghc-regress/codeGen/should_run$ '/home/ian/ghc/darcs/st2/ghc/stage2-inplace/ghc' -fforce-recomp -dcore-lint -dcmm-lint -Dx86_64_unknown_linux -dno-debug-output -o cg052 cg052.hs -O -fasm -funbox-strict-fields
testsuite/tests/ghc-regress/codeGen/should_run$ ./cg052
ok
cg052: internal error: stg_ap_v_ret
(GHC version 6.9.20080902 for x86_64_unknown_linux)
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
zsh: abort ./cg052
I'm not sure what's going on, but it seems to be repeatable.
