[arch-haskell] haskell-src-exts: Illegal instruction (core dumped)

[Nicola Squartini]

Hi,

I already mentioned this problem earlier on this mailing list, but now I
have some extra information.

It's the following (on GHCi):

Prelude> :m Language.Haskell.Exts
Prelude Language.Haskell.Exts> parseFileContents "main = putStrLn \"Hello
World\""
Loading package array-0.5.0.0 ... linking ... done.
Loading package filepath-1.3.0.2 ... linking ... done.

Loading package pretty-1.1.1.1 ... linking ... done.
Loading package haskell-src-exts-1.15.0.1 ... linking ... done.
Illegal instruction (core dumped)


This affects everything that depends on haskell-src-exts, like hlint and
stylish-haskell.
The bug shows up only on my two AMD Athlon II X2 computers, but not on my
other Intel Sandybridge.

I think it is related to -fllvm flag because I didn't have this bug with
the 1.15.0 version, which didn't have the flag.

Can someone with similar AMD architecture try to replicate it, please?

Thanks

Nicola
