Subject: Avoid segfaults on MS-Windows when invoked with --version
X-Git-Tag: emacs-29.0.90~1910^2~295^2~4
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=58965d91e7fb5a26a5422357f44d6e841f67db74;p=emacs.git

Avoid segfaults on MS-Windows when invoked with --version

* src/emacs.c (main): If invoked with --version, call
'init_bignum' before calling 'format-time-string', as that is
needed for safe manipulation of bignums in timefns.c.
