It could be that you have updated something else on your system, not
just Emacs's sources, and that indirectly caused the problem even in
builds that previously worked well.  If that is the case, it might
mean the problem which causes this is not due to some recent change in
Emacs, it was always there.

With that in mind, can you describe the sequence of actions that you
are using, after which these errors usually appear?  Also, are these
errors 100% reproducible, if you replay the same actions , or do they
appear only sometimes?
