Hi everyone, I ran into the "x = ++x + ++x" type of problem, where someone (not me) put in some undefined behavior. >:-( GCC can warn about those situations, which is very helpful. Presuming someone is paying attention, and the appropriate warning is enabled. (It's even more interesting undefined behavior, since it does different things on different platforms, and even on the same platform at different optimization levels.) What I want to do is have those undefined behavior situations is to have GCC emit in an assert or an abort. (If I could just make *THAT* one single warning be an error but not *ALL* warnings-into-errors, that'd be good too.) After all, the behavior is undefined, and an assert or an abort is well within the scope of what a compiler could do. Any guidance as to how I could accomplish this feat with GCC? Thanks, --Eljay
