#2 VBAP UGen crashes SC.app with uninitialized buffer

[ZLB]

When using VBAP.ar with an uninitialized buffer in the internal server of SC on the mac app, the whole app crashes.

Running

x = { |azi = 0, ele = 0, spr = 0|
VBAP.ar(8, PinkNoise.ar(0.2), 0, azi, ele, spr);
}.scope;

causes SC.app to crash:
