DragonFlyBSD

Hi,

While trying to update my packages, ruby coredumps with an odd message but clear
message:

dfbsdx64# ./rpkgmanager.rb
2011-03-24 21:45:19: Reading wanted.db...
2011-03-24 21:45:19: Reading wanted.db... Done

/home/source/gitorious/rpkgmanager.git/pkgtools.rb:737: [BUG] Bus Error
ruby 1.8.7 (2011-02-18 patchlevel 334) [x86_64-dragonfly]

So I tried to gdb it:

Segmentation fault (core dumped)

And gdb also segfaults!

What's also odd is the number of frames in the gdb segfault. I reached frame
2101, so I stopped it.

(...)
#2101 0x0000000000476c6d in frame_register_unwind (frame=0x90, regnum=1,

I've uploaded the files (ruby18, ruby18.core, gdb, gdb.core) to leaf:
