Subject: Handle disappearing temporary stdout file gracefully
X-Git-Tag: v3.1.9~1
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=17791e1e460aec9c0efc1edbd031e975b81c1855;p=thirdparty%2Fccache.git

Handle disappearing temporary stdout file gracefully

If the temporary stdout file has disappeared, it's most likely because
another ccache process is doing cleanup on a too small cache.
