Subject: patch 9.2.0462: MS-Windows: workaround for assert error on GUI
X-Git-Tag: v9.2.0462^0
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3a1ac7ced28179a5b39a7135b5c242ec8bc06797;p=thirdparty%2Fvim.git

patch 9.2.0462: MS-Windows: workaround for assert error on GUI

Problem:  When Vim is built with debug mode, gvim causes an assertion
          error and stops working when running on Visual Studio
          Debugger.
Solution: Stop calling _set_fmode() if not needed (Ken Takata).

closes: #20181
