nevermind - stupid error on my part - i somehow managed to get two copies of Symbiosis.mm in one target.
now i'm getting another error - but only when validating in 64 bit:
during render tests i get
[SoundHack: +delay](0x7fff72f10960) AU kAudioUnitInitializeSelect
[SoundHack: +delay](0x7fff72f10960) VST resume
[SoundHack: +delay](0x7fff72f10960) AU GetPropertyInfo: unknown property id: 29
property 29 should be
kAudioUnitProperty_InPlaceProcessing
not really sure why auval is calling that for 64 bit….
