I have the following problem with the latest -current.
Running the following trivial csh script panics the machine each
time:
#!/bin/csh -f
nonexistentfile1
rm nonexistentfile2
If you replace csh with sh, it doesn't seem to panic anymore...
I've sent a PR for this yesterday, but of the two persons who
replied, no one was able to reproduce it (one of them maybe because
his kernel was dated December 9th). I'd like to know if I'm just
having hallucinations or somebody else can reproduce the bug (It
works both on a Cyrix P166+ IDE 32Mb and an AMD K6, 64Mb, SCSI).
It's a problem with exec_aout_imgact() getting a NULL imgp while
it's called by execve() with a non-NULL imgp. Maybe the stack is
at an odd location in memory? The system doesn't panic otherwise,
only when I happen to run the script.
Here's a stripped-down kernel config which panics:
machine "i386"
cpu "I586_CPU"
ident ASTERIX
maxusers 30
options DDB
options INET #InterNETworking
options FFS #Berkeley Fast Filesystem
options "COMPAT_43" #Compatible with BSD 4.3 [KEEP THIS!]
config kernel root on sd0
controller isa0
controller pci0
controller ncr0
controller scbus0
device sd0
device sc0 at isa? port "IO_KBD" tty irq 1 vector scintr
device npx0 at isa? port "IO_NPX" flags 0x1 irq 13 vector npxintr
pseudo-device loop
