Hi,
I'm using 211bsd (Version 447) and found that a 'here document' in tcsh
leads to a kernel panic. It's absolutely reproducible on my system, both
when run it on my FPGA PDP-11 or in simh. Just doing
tcsh
cat << EOF
is enough, and I get
ka6 31333 aps 147472
pc 161324 ps 30004
ov 4
cpuerr 20
trap type 0
panic: trap
syncing disks... done
looking at the crash dump gives
cd /etc/crash
./why 4
Backtrace:
0147372: _boot(05000,0100) from ~panic+072
0147414: _etext(011350) from ~trap+0350
0147450: ~trap() from call+040
0147516: _psignal(0101520,0160750) from ~trap+0364
0147554: ~trap() from call+040
so the crash is in psignal, which is afaik the kernel internal
mechanism to dispatch signals.
Questions:
1. has anybody seen this before ?
2. any idea what the reason could be ?
With best regards, Walter
