Subject: Fix build failure on MacOS by initialising a variable which was
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=d54bbdadeef015f9360dddfd6284b72f9937ca94;p=sgt-puzzles.git

Fix build failure on MacOS by initialising a variable which was
reported as potentially-unused. (In fact, as far as I can tell, it's
only ever uninitialised in assertion-failing code paths, so not a
real bug.)
