Reproducible crash

[extrowerk]

I have 2 computer running Haiku, both have Vision configured to ocnnect to the same znc bouncer. If i start Vision on computer A, and the on computer B, the one running on A will crash. It works in both direction, 100% reproducible.

A workaround was : i disabled the freenode server in znc, now it doesn't crashing anymore.

On IRC i got this hint:

<mcrcc> I have a hunch that it may be because 'ulong addr = inet_addr...' in ParseCmd.cpp should be 'in_addr_t addr = inet_addr...' and the types may not be the same size
<mcrcc> line 1174
