Bug ID: 79184
Summary: -Wint-in-bool-context triggered erroneously in
template parameter
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jagerman at jagerman dot com
Target Milestone: ---
When compiling the following with -Wint-in-bool-context under a recent snapshot
of g++-7:
template <bool> void f(int) {}
template <int> void f() {}
int main() {
f<1*1>();
}
`g++ -Wint-in-bool-context t.cpp' produces the warning:
t.cpp: In function 'int main()':
t.cpp:5:8: warning: '*' in boolean context, suggest '&&' instead
[-Wint-in-bool-context]
f<1*1>();
~^~
But this is wrong: the template parameter here is int, not a bool, and is not
in bool context. The existence of the templated overload, despite not being
called in this context, appears to be falsely triggering the warning.
