I don't have much proof, but I remember this to work differently back in TBC.

Check out http://www.youtube.com/watch?v=SsiXmo5R8go in 720p at 5:04-5:05.. getting "Target not in line of sight" while Evocation and Frost Nova are available.

https://github.com/TrinityCore/TrinityCore/issues/3940 is connected to this - also Death Knight's (DK) Death and Decay is affected.

I'm guessing that https://github.com/TrinityCore/TrinityCore/issues/2967 is also somehow related since attempting to cast a spell while the global cooldown is active results in an error (that by itself triggers GCD, but since that one is already active, it's ignored). However, if the cast attempt is made at the end of the GCD, it will be triggered once more and with perfect timing or network lag, the spell will never be cast - had GCD trigger at least 3 times in a row by "nothing".

The point is that AFAIK no errors (the red messages - not "immune") should ever trigger cooldowns of any kind.
