[gentoo-dev] depscan.sh segfault issue

[gentoo-dev] depscan.sh segfault issue

[jano]

Hi,

my depscan.sh segfaulting issue is still here.  I upgraded baselayout to
next version (1.6.5 from 1.6.4), but couldn't figure out how to make it
work.
Per rec of some people on irc, I ran depscan.sh through strace.  Sorry, i
have no idea how to debug a seg fault, but the output of depscan through
strace is here, for anyone interested:

http://www.portablehole.net/~jano/fridge/strace.depscan.sh.bz2
(28k, decompresses to 3.5MB file)

system specs:
kernel 2.4.14 with preempt and xfs patches
p3 800x2, 512MB ram
via apollopro chipset

Ahhhh poop, feel like a dork replying to myself.  But I made some progress.

I've narrowed down the problem to the gpm init.d script.  For some reason,
depscan doesn't like it at all.  I messed around, and found an interesting,
albeit STRANGE, pattern:

if I named gpm to:
gpm-
gpm~
gpm1
gmp
gpf
mouse
mouse-script

and tried to add it using rc-update (makeing sure it was removed first),
depscan would segfault.  However, when I named gpm to
testing
test
blah
foobar
it worked great.

I also tried commenting out everything inside the script, moving stuff
around, blah blah blah, no go.

Uhhhm.... HUH???????????????????????  This is mucked up. :D

Yep.  I cant think it being depscan.sh itself, rather maybe a 
bug in bash, or something.  Try another version bash, or maybe
remerge bash with less optimizations.

Could you please change the top line of /etc/init.d/depscan.sh to

    #!/bin/bash -x

then run your test with the script named "gpm", and send me the output?
Don't send it to the list... it will be lengthy.  You can run rc-update
as follows (or with whatever arguments you're using).

    rc-update add gpm default &> rc-update.out

Thanks,
Aron

P.S. No guarantees... I'm particularly busy at the moment, but I'd like
to take a look.

Aha, that did it.  Thanks for the bash -x.  Here's the problem.  The gpm
init script has:

need {
need localmount
}

at the top.  It should've been "depend {}", not "need{}".

Looking at files/gpm.rc6, seems this has been fixed, but fixed after I
installed it.  I wonder why it "worked" if I renamed the script to test?

Problem solved :)
