Executable error in Decompile Tab

[jjak0b]

I was searching some functions and i saw an error printed inside a decompiled gsc function.

Game: Black Ops 3
FF: core_patch.ff
File: scripts/shared/vehicle_ai_shared.gsc
function: collision_fx

function content on Decompile tab :

/*

	Checksum: 0xED4A3458
	Offset: 0x1688
	Size: 0x7B

	Flags: None
*/
function collision_fx()
{
System.InvalidOperationException: Stack empty.

It seems to contain a ternary operator, which the decompiler currently doesn't handle, weird it results in a stack empty, because in theory there should actually be more items than expected on the stack. Source version in Modtools, to be looked into
