I think that this is just a side effect, with reworked subme possibly 
making your encode going through code it was not going through before, 
considering your encoding params.

It is much more likely that the issue started on one of those changes:

(yes, I know: 10 revisions to test)

All of those introduced some changes within the ASM code, and at this 
point it is very likely that your issue is related to ASM code 
(precisely: alignment issue)
