Comment (by duncan):
bytestring hGet is now fixed in the darcs repo. Also audited for other
cases in the bytestring package.
Looking at the GHC.ForeignPtr code, the following probably need fixing:
{{{
mallocForeignPtr
mallocForeignPtrBytes
mallocPlainForeignPtr
mallocPlainForeignPtrBytes
}}}
In the case of the non-"Bytes" versions that use `Storable`, that'd be a
check for the Storable sizeOf function returning a negative value.
