For regressions, yes, but I don't think this is a regression. > Regarding 4.9, gcc fails to complain at all when -pedantic is passed, > even specifying -std=c++03. > Please let me know if this is truly a bug, in which case I could also > fix it for the latest version as well I believe it's by design. The C++11 standard says in [expr.reinterpret.cast] paragraph 8: "Converting a function pointer to an object pointer type or vice versa is conditionally-supported. The meaning of such a conversion is implementation-defined, except that if an implementation supports conversions in both directions, converting a prvalue of one type to the other type and back, possibly with different cv- qualification, shall yield the original pointer value." G++ has always supported it, but we previously warned with -pedantic that it was not standard-conforming behaviour. Now it is conforming (as long as we document the implementation-defined meaning of the conversion).
