I have found the cause of the crash. The fix requires updated binaries
for both AdminMod and MetaMod (and any other 3rd party plugins such as
the closed source AMX).

You can download the fixed binaries from:
http://www.adminmod.org/downloads/metam ... _25058.tgz

Just extract the file from the root hlds directory. The file is 424976
bytes long and its md5 is:
cb2f5b7b531cb80581aeab286f611a29

I will be posting details of the problem to the hlds_apps list (and to
the author of MetaMod).


For the technically inclined:
The engine interface used by MetaMod differs from the engines version in
some of the parameter sizes for various functions. This mis-match causes
MetaMod to access the wrong part of the engine when calling a function,
which results in undefined behavior. This problem has been around since
steam was released, luck just stopped it from crashing until now (the
differences are subtle).
