Can you check with gdb if it is failing for the same reason as Firefox
and Xdvi fail for me?  See

  http://www.macs.hw.ac.uk/~jbw/colinux-floating-point.mbox

for my messages containing details of how to check a core dump with
gdb.  If you are seeing the same kind of failure I am seeing, then
some instruction to transfer a value into a floating point register
will have yielded a wacky value in the register, perhaps a few
instructions before the crash.  For me, I always see the programs
crash when they use cvttsd2si to convert the content of a floating
point register to an integer, but it seems something has already gone
wrong a few steps before the crash.

Also, what precise CPU do you have?  I have an Intel Pentium M
(mobile) CPU.

If you are using devfs (e.g., if you are using Gentoo), then the
pseudo file /dev/cobd1 will not be created.  Instead, devfs will
create /dev/cobd/1.  See the earlier messages on the mailing list
about this.
