Keep getting segment violation

Hi there,

I keep getting this segment violation and i have the feeling i broke something. I am running Slackware Linux and i was trying to upgrade TCL to version 8.4.6 using the package management system. When i went into the bot and tried to load a module, the bot crashed. An attempt to restart the bot failed with this as the result:

[00:59] Now listening for livestats connections on port 8033
[00:59] * Last context: stats:tclstats.c/66 []
[00:59] * Please REPORT this BUG!
[00:59] * Check doc/BUG-REPORT on how to do so.
[00:59] * Wrote DEBUG
[00:59] * SEGMENT VIOLATION -- CRASHING!

I tried disabling the stats module, but that only lead to something else crashing the bot, this was the result of disabling the stats mod:

[01:23] Module loaded: gseen
[01:23] Loading language "nl" from language/gseen.nl.lang...

[01:23] * Check doc/BUG-REPORT on how to do so.
[01:23] * Wrote DEBUG
[01:23] * SEGMENT VIOLATION -- CRASHING!

So that didn't work. I took a look at the DEBUG file and this is what i came across:

Does this make sense to anyone out there? i am completely stupified.

recompile eggdrop

Installation Instructions for gseen/stats.mod:
Put gseen.mod.1.1.0.tar.gz in ~/eggdrop1.6.17/src/mod/,
and unpack it (tar xfz gseen.mod.1.1.1.tar.gz). Change directory
back to ~/eggdrop1.6.17/.
Now just do what you've done when you compiled your bot:
"./configure"
"make config" (you can skip this command on eggdrop 1.4)
"make"
"make install"
don't forget to edit gseen.conf completely, and copy all the language files!

happy seen'ing

I have to say that neither the stats nor the gseen module are the problem for that matter because i have disabled both modules in the conf file and the bot still won't start. i've recompiled many times and that didn't solve anything either. i just have the feeling that a component of the linux box is broken somehow. can someone tell me which system libs the bot uses, which system utilities and which tcl version, which components tcl relies on etc. i've been trying different stuff since last night and i honestly can't make sense of it any more.

I also got this output when i disabled the stats and the gseen module:

As you can see, it is a different segfault altogether. this time it's in tclhash.c/238. check the DEBUG file reveals:

To me it looks like it's crashing when trying to interpet one of the tcl scripts.
Try removing all of them, and then readd them one by one, to find the one causing the problems.

i would like to thank you all for your help. i found the problem to be a faulty megahal module. it broke somehow and caused the entire bot to halt. the thing that confused me was the fact that it kept giving different error msgs and since i am not a programmar, i didn't understand what was going on.
