i use green-card with ghc's FFI export to sth like
Haskell - C -- Haskell
the program is just arithmatic operations. the program seg fault
in the callback from C to Haskell. anyone whether it is a bug?
There aren't any known bugs, but there
I have some code that uses FFI capabilities to associate
previously allocated
memory with a structure akin to a ByteArray and allows
Haskell land to read
and write to the C side of things.
I use ForeignPtr and associate a destructor to allow the GHC's garbage
collector to clean up
hi,
i've found the reason with someone's help. it is because i used
%code instead of safecode in the gc file where i did callback.
thanks!

I tried the simple test:
main =
do
d - connectTo localhost (PortNumber 80)
hPutStr d GET / HTTP/1.0\n\n
hFlush d
c - hGetContents d
