Could be, although the changes introduced there don't do anything by
default, only if you customize a new variable.
The problem sounds like it's related to some memory allocation, and
the abort-redisplay feature didn't add any such allocations to the
code.
However, since I have no idea what vterm does, and from the backtrace
it sounds like it replaces some very low-level code in Emacs, such as
the implementation of recenter, I really cannot say. Someone who
knows about vterm will have to debug this.
