Hi,

I've previously used Bloom filters on 32-bit Linux with some success. However, after upgrading to 64 bit, my Bloom filter applications crash or misbehave in random ways.

So: is anybody successfully using Bloom filters on 64 bit computers?

Although I'm not clear on why it would cause crashes (SEGV, infinite looping, etc), my prime suspect is the hashing function used. This is from C and returns a uint32, but it is imported to return a CInt, which I suspect is 64 bits.

On 64-bits Int can be either 32 or 64-bit. In theory it can be anything. It should use Data.Word.Word32 Regards
