I got access to a box of a friend and he gave me a ssh2 account. Downloading, unpacking and compiling eggdrop worked well without errors. But after I wanted to start it there was a segfault, so I started with -n to see more debug messages.

Btw, the configuration worked already on other box. Dunno what here is the problem. Any hints?

Read the file BUG-REPORT that comes with the source.
To gather any useful information on what actually caused the segmentation fault, a core dump with backtrace would be needed.

Did you read BUG-REPORT?
If not, I'm quoting the relevant part from it:
| Code: | 4.8) If the bot dumped a 'core' file when it crashed, it would be *very*
useful if you could paste gdb's output during the following steps:
First call gdb
$ gdb eggdrop -c core
and then enter 'bt' on gdb's command line:
(gdb) bt
Keep your core file for at least one week, so that the dev team
can ask for further information if needed. However, don't send
us the core file unless we ask for it.
NOTE: If this is a bug you can reproduce, please compile with
make debug and follow the above step. It can greatly help
find and fix the bug. |

One of the big issues with most reports shown in those archives is the lack of backtraces on coredumps... Without that, tracking down bugs is quite similar like searching for a needle in a haystack while being blindfolded.
The 1.6 tree, I guess, is'nt being much developed these days for numerous reasons. One I've been told is the lack of developers with time/interrest in enhancing the 1.6 tree, aswell as fixing bugs within it. There is a memleak in the notes-module that I've reported long time ago, that I belive is still unadressed (albeit a possible solution has been provided).
Nevertheless... post the result of the backtrace here aswell, and we'll see what comes up..
