Subject: [ruby-core:40303] Re: BitField extension

Great thanks! That really was the problem.

I'm now having trouble clone'ing my object though. I'm running into a
segfault in my code when I call bitfield.clone. I made my sources
available at http://xnorfz.de/stuff/BitField.tar

Could it be that ruby doesn't now about the memory allocated by the
dynamic_bitset::resize? I've also included a test script that segfaults.

Cheers,
Fabian

I haven't been able find the source of the problem as the segfault occurs deep inside the ruby core. Does anyone see anything wrong with my code so far?
