I've isolated the issue to a ruby extension that has 140 lines of C
code and shows the same (or a similar) segfault.

If this is helpful, you can clone it here:
git://github.com/ender672/minigiri.git

Or view the C code here:
https://github.com/ender672/minigiri/blob/master/minigiri.c

Some things it does may seem strange, but that is because it tries to
match what Nokogiri does.

So far, I am unable to see why it crashes.

Cheers,
Tim
