Subject: Fix crash on loading garbage game file
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=95ca32189a095e0ef60ca6391bc0192695d195dc;p=xboard.git

Fix crash on loading garbage game file

XBoard crashed when a game file contained a PGN game result before
any valid game start, because data would be written in a game-list
node that did not exist yet. This would occur frequently when garage
was read; basically any asterisk in the data would do it.
