This is due to a bug in the hfs-plus utils (mol contains a stripped
compiled-in copy whose purpose is loading the MacOS ROM file). In
fact, a similar segmentation fault has been reported if one tries
to use the hfs-plus command line tools directly to copy the MacOS 
ROM file to the linux side.

I actually added the symbolic backtrace in order to get a better 
idea what goes wrong here. I'll see if I can locate the bug from
this information. If not, perhaps the author of the hfs-plus utilities
has some idea. (I did check for recent bug-fixes some time ago, but
I couldn't find any that would affect this).

The main problem is that I can't reproduce the bug locally. If
someone who experience this bug could track it down and fix it,
it would be great. Another possibility is giving me remote
access (the a machine should preferably be located in Europe,
since the latency accross the Atlantic is quite bad for the blood
pressure).

If worst come to worst, I can always rewrite the hfs-plus code.
The hfs-plus utils provides more functionality than mol
really needs. Reimplementing only the basics wouldn't take
all that long (and the code size would be reduced).

Oh... and there is a workaround. Transfer the 'MacOS ROM' file
to the linux side and add a 'newworld_rom: /path/to/rom'
line in /etc/mol/molrc.macos. Just make sure the file
is not MacBinary encoded in the process.
