hmm - the functions on the stack trace haven't changed recently
(except of course for the large case-statements where again nothing
on this stack appears to have changed recently, e.g,. in the past year).
There were some recent fixes/updates in wcwidth.c, which should not make
a difference, unless there's some sign-extension or similar bug.
Is this something that you might reproduce, to provide test-data?
