Hi, there
I am using Greencard with Hask's foreign function export. I found
the following program can cause seg-fault. Anyone has any idea? BTW,
if I replace greencard with Hask's foreign function import, there
is no such error.
in ABC.gc:
foreign export ccall h_add h_add :: Int - IO Int
Hi there,
we would like to adapt a Haskell parser for whatever purposes, and looked
for one in the ghc distribution. However, in ghc 5.02, we found two
happy-generated parsers, one in ghc/compiler/parser and one in
hslibs/hssource which both look similar, but seem to be slightly different

Hi, I want to invoke the C-function 'dlsym', which has three
possible options for a parameter of type (void*):
- NULL
- void* to a string, i.e. CString in Haskell
- RTLD_NEXT = (void *)(-1)
The first two ones are no problem, I can use a CString and
'nullPtr'. For the last one, I have the

There, it crashes for me even on the 2nd invocation:

How does this explain the two differing behaviours?
And why didn't it happen in a compiled version?
Because the 'optlen'
At [EMAIL PROTECTED] I asked the following:
this works

this doesn't work
newtype Exists f = forall x . E ( f x)
Hugs accepts both.
It there a reason why existential quantification does not work with a
newtype, or is it just

It kind of decreases the readability... ;-)
I'm interested in any ideas. Would like a full picture of the different

The trouble here is the usual one: accumArray is lazy,
and simply accumulates a giant closure in each array slot.
Then, when it is evaluated, the stack gets big.
There should really be a strict accumArray, just as there
should be a strict foldl. There isn't in Haskell 98, but if you
