On Solaris 11 and Linux, I find
Considering static EnumStatusCode ValueHelper::getLocalizedText(const
ValueStruct*, LocalizedText&)/26 with 17 size
to be inlined into static LocalizedText ValueHelper::getLocalizedText(const
ValueStruct*)/15 in (null):0
i.e. fprintf(NULL), which doesn't work in every libc.
