No, the crashy Bengali sequences are reasonable to have; like I mentioned ZWNJ has semantic meaning with bengali vowels.

I am judging by this statement in the blog post:
In Bengali and Oriya specifically, a ZWNJ can be used to force a different vowel form when used before a vowel (e.g. রু vs রু), however this bug seems to apply to vowels for which there is only one form
This seems to say that the ZWNJ has a meaning before vowels that have different forms, but the crash happens with vowels that only have one form, where the ZWNJ has no effect. Maybe I am misreading?

Yeah, you are.
I'm saying that this crash _also_ applies to vowels with one form.
রু was the original Bengali crash, and that has two forms. I'm saying it's less likely to be related to the zwnj-vowel interaction because it also occurs for vowels where such interaction doesn't exist.
