[Haskell-cafe] Re: LLVM backend building segfault (Louis Wasserman)

[Jonathan Fischoff]

I got this too, on windows. On linux I got a similiar issue, but I think the
message was different. I ran the ghc stage2  with valgrind and it complained
about there being an invalid instruction. I wonder if it is a 64bit thing.
Anyone been able to build the LLVM backend with a 64 bit machine?
