--- Comment #4 from Xi Ruoyao <ryxi at stu dot xidian.edu.cn> --- Created attachment 40950 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=40950&action=edit Another way to show this bug This test case also exploits this bug. In this lim<long> should be the same as limlong, but g++ (trunk) only warns about the latter: ~~~ pr69138-2.cpp: In function 'long unsigned int limlong(bool)': pr69138-2.cpp:23:16: warning: integer overflow in expression [-Woverflow] return b ? -limits<long>::min : limits<long>::max; ~~~ No warnings generated for lim<long>(bool).
