The program illustrates a form of programmer brain- damage where the programmer has neglected to type the 'return' keyword. This bug can be extremely difficult to find but many thankfully, many other compilers will catch this and issue a warning/error. For instance, SGI's compiler warns that: "Non-void function "foo" (declared at line 1) should return a value." int foo() { 3; } int main() { return foo(); } Please modify gcc so that it issues a warning when it encounters such mistakes. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
