FPC IRC channel
From Free Pascal wiki
The official IRC channel for the free pascal compiler is #fpc on irc.freenode.net . Most of the core developers are Europeans, so choosing a decent European hour may improve your chances to contact them ;-).
Current logs are at http://www.elesoft.net/lift/lift.php?prefs%5Bshowtype%5D%3Dcurrent%26prefs%5Bchannel%5D%3D100
There are also some older logs here, but this has stopped logging as of Oct 2012.
