`gcc-4.0 -Wall -O2' on the attached piece of code produces the following warning:
s.c: In function 'main': s.c:15: warning: control may reach end of non-void function 'xtoi' being inlined which doesn't make much sense as assert_failed() is known not to return. If I remove the `if (1)', the warning disappears. The warning doesn't appear in gcc 3.4.4. -- Summary: Bogus "control may reach end of non-void function ... being inlined" warning Product: gcc Version: 4.0.0 Status: UNCONFIRMED Severity: minor Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: mj at ucw dot cz CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: i686-pc-linux-gnu GCC host triplet: i686-pc-linux-gnu GCC target triplet: i686-pc-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21800
