Subject: fontconfig, at least as used by GIMP and/or PangoFT2 on Windows, crashes
X-Git-Tag: fc-2_2_93~7
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=f4c52909ab5321df608fe7af2da3edcab48818d9;p=fontconfig.git

fontconfig, at least as used by GIMP and/or PangoFT2 on Windows, crashes
    when trying to save the cache if config->cache is NULL, which happens
    if FcConfigHome() is NULL. Guard against that by using the temp folder
    in that case.
