It's more a problem than a bug...
Instancing:
1 Mesh that is applied to multiple objects.
I subdivided the objects 2 times...
but sometimes, I oversaw some meshes, that just had subdiv 1 instead...
-> no error, no fullstop and close window, no warning, but an infinite export time... more or less
Can you add an error message for that, that imediately will stop exporting?
