eggdrop 1.6.7 and 1.6.8 SEGFAULT on DEC Alpha Unix 4.0D

I wrote a message about this after release of eggdrop 1.6.7 but no one responded. Again:
I make eggdrop 1.6.8 and installed it. After that by starting it, it SEGFAULTS with the following:

Please help! Version 1.6.6 runs perfectly. 1.6.8 also works fine on Linux. I also tried to use the --disable-cc-optimization option. On another DEC machine the same thing occurs.

Try thr latest 1.6 development code (AKA CVS).

See the readme files with eggdrop, for information on how to obtain them.

A few days ago I tried the last CVS code with the same result (code from 21/01/2001)

I checked the code and found the following:
After commenting out the following line in tclhash.c, function init_binds() the bot starts without the error.

add_cd_tcl_cmds(cd_cmd_table);

This command didn't appear in eggdrop 1.6.6. It seems to bind callbacks for the TCL commands "bind" and "unbind". I use TCL 8.3.4, so the following shold be incorrect and cause the SEGFAULT:

void add_cd_tcl_cmds(cd_tcl_cmd *table)
{
int *cdata;

while (table->name) {
cdata = (int *)nmalloc(sizeof(int) * 2);
clientdata_stuff += sizeof(int) * 2;
cdata[0] = (int) table->callback;
cdata[1] = (int) table->cdata;
Tcl_CreateObjCommand(interp, table->name, utf_converter, (ClientData) cdata,
cmd_delete_callback);
table++;
}
}

After compiling eggdrop 1.6.9 the same error occurs... Nobody has done something

If someone has an idea I could test it on my machine!

If I could get an account to use for eggdev -- we would be better able to figure out the problem. Where did you report the problem? You should send bug reports to bugs@eggheads.org (this forum is not an official place to report bugs in eggdrop) .. if you did and we missed it, I'm sorry and hopefully it can be resolved for 1.6.10

I wrote this message not only to this forum even to the eggheads@eggheads.org mailing list.
I will wote a separate bug report, too.

The problem is solved now, It was a missing NULL in tclhash.c
