Comment:
I've got similar problem on x86-64 Linux but only with ghc compiled code,
not
ghci. For me `4038` simply segfaults when compiled. The interesting thing
is
that if I change the test to
{{{
f :: Int -> IO Int
f 0 = return 42
f n = do
putStrLn $ "first: " ++ show n
f' <- wrap_f_io f
putStrLn $ "second: " ++ show n
f_io f' (n-1)
}}}
Then the result is:
{{{
~/develop/ghc/inplace/bin/ghc-stage2 --make -fforce-recomp 4038 -rtsopts
-debug && ./4038
[1 of 1] Compiling Main ( 4038.hs, 4038.o )
Linking 4038 ...
first: 1000
second: 1000
first: 999
second: 999
first: 998
second: 998
[...]
first: 501
second: 501
first: 500
second: 500

}}}
When running gdb on it
{{{
[...]

second: 501
first: 500
second: 500
Program received signal SIGSEGV, Segmentation fault.
0x00000000006e5ce3 in stg_ap_p_info ()
}}}
So it segfaults also in `stg_ap_p_info`.
This seems a bit too similar to be unrelated, so maybe the issue is not
limited
to OS X? Or am I just hitting different bug?
