String::doubleToStringWithDecPlaces() is broken under 10.3.9. Same app, compiled for 10.3, works under 10.4, not under 10.3.9.
I get an assert: assert (*t == 0);
I’m guessing CharacterFunctions::printf (buffer, bufSize, T("%.9g"), n) isn’t working, since if I make the function use the first branch it work fine.
