Description Justin Dolske [:Dolske] 2011-12-14 23:38:21 PST
5th section in

V502 Perhaps the '?:' operator works in a different way than it was expected. The '?:' operator has a lower priority than the '+' operator. 291

bool ots_gdef_parse(...) {
  const unsigned gdef_header_end = static_cast<unsigned>(8) +
    gdef->version_2 ? static_cast<unsigned>(2) : static_cast<unsigned>(0);

I think there could be written like this.
const unsigned gdef_header_end = static_cast<unsigned>(8) +
  (gdef->version_2 ? static_cast<unsigned>(2) : static_cast<unsigned>(0));

This bug is no longer present on trunk. The fragment in question has been restructured (upstream in OTS rev.66) and does not have this problem. The fix was imported into Gecko as part of bug 699420.
