--- Comment #4 from Bruce Adams <tortoise_74 at yahoo dot co.uk> 2011-11-24 17:09:56 UTC --- Shouldn't integral conversion rules apply if the types of the second and third arguments to a conditional expression differ. So zero should be converted from the default int to a char as presumably the older version of gcc did. Perhaps a language lawyer could explain why this is or isn't a bug. Though obviously warnings are not covered by the standard. Note: (haveBar?bar_:(char)0) is not an acceptable workaround for C++ if -Wold-style-cast is used (which is in my experience typical). It would have to be (haveBar?bar_:static_cast<char>(0)) which is a notch higher in annoyingness.
