You're right, it does give a "warning" if you use -Wall. But on the default warning level, the program has two major errors, which should not be considered warnings. It has a non-void function, which is used, not returning a value, and a void function (main()) returning a value. Every other compiler I've used spits out error messages for these problems. This is a big problem, not a "INVALID" concern. Also, did you notice the void function rguenth at gcc dot gnu dot org wrote: > ------- Comment #1 from rguenth at gcc dot gnu dot org 2006-05-06 14:57 > ------- > It says "warning: control reaches end of non-void function", also the code is > not invalid, but undefined, thus you get a segfault. > > > -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27456
