Some days back I sent a message about a kernel panic, included
below, caused by the SunOS binary of Mathematica on NetBSD 1.4.2
on a Sparc IPC with a generic kernel. I now have a crash dump,
and the backtrace gives
(gdb) target kcore /var/crash/netbsd.3.core
panic: amap_lookups: offset out of range
#0 mi_switch () at ../../../../kern/kern_synch.c:633
633 cpu_switch(p);
(gdb) bt
#0 mi_switch () at ../../../../kern/kern_synch.c:633
#1 0xf002f340 in tsleep (ident=0x0, priority=4, wmesg=0xf00ce578 "scheduler",
timo=0) at ../../../../kern/kern_synch.c:371
#2 0xf00ce718 in uvm_scheduler () at ../../../../uvm/uvm_glue.c:436
#3 0xf001f6e4 in main () at ../../../../kern/init_main.c:420
It would be nice if this can be fixed. I don't know what to look for,
if you point me in the right direction I'll try to do whatever I can...
