Well, I'm not sure what the difference is between your 2.6.7 and the one
that I just built, but:
[ccl-0.14/ccl] gb at z2> uname -a
Linux z2 2.6.7-gentoo-r13 #1 Tue Aug 10 17:14:03 MDT 2004 ppc 7455, altivec supported PowerBook6,3 GNU/Linux

Welcome to OpenMCL Version (Beta: Linux) 0.14.2-p1!
If you could try running this under GDB, that might tell us something.
First (to make things easier), ensure that ccl/.gdbinit is a link to
shell> cd ccl
shell> ln -s lisp-kernel/linux/.gdbinit .gdbinit
shell> gdb ./ppccl
(gdb) break start_lisp
If that gets to the breakpoint at 'start_lisp', that suggests that the
segfault you're getting happens after lisp kernel initialization.
If you get a segfault before reaching that breakpoint, gdb would probably
be able to say where it's happening. Since it doesn't seem that I can
reproduce this, that'd be very helpful to know.
