Thanks.  Too much is involved here, but my money is on consult: I see
in its code several places where it matches file names in a way that
can only work on Posix systems (i.e., assuming absolute file names
begin with a slash, not with a drive letter).  Since
consult-recent-file is in the Lisp backtrace, it's a definite
possibility.

Another possibility is that some of your customizations includes such
a file name.

Anyway, now at least that crash shouldn't happen anymore.

You can now remove the added condition and the call to emacs_abort
from the code.  Please run for a while and see if there are any other
crashes like that one, which yield a zero code address.
