If the value on which to type-switch was already set (i.e. a variable), there was no problem. But if it had to be obtained through a complex expression (func call, array index, etc...), then the code to retrieve the value prior type-switch was not scheduled. This is now fixed. This issue is nasty because the behavior is silently changed, leading potentially to further unrelated issues or runtime panics. Fixes #1444.
