Bug ID: 67216
Summary: false is still a null pointer constant
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: potswa at mac dot com
Target Milestone: ---
false should not convert to pointer types since C++11. This program is ill
formed in C++03 and well formed in C++11.
struct s {
s( long ) {}
};
struct t {
t( void * ) {}
}
void foo(s) {}
void foo(t) {}
int main() {
foo(false);
}
