workaround

this is caused by the same bug that causes Issue #14214: too many "code comma
expressions".

i'm almost sure that both bugs triggered by the same code path, as i did a
quick workaround for #14214 (not failing on processing too many OPcomma
blocks), and it fixes this bug too.

yet i'm not familiar with codegen, so i will not mark this as duplicate, as
this need further investigation from a person with codegen/optimizer knowledge.

i attached the workaround for those who want to dive into optimizer. it
degrades optimizing quality in such pathological cases, but it at least allows
optimizer to process other code.
