Bug ID: 49375
Summary: statically recognizable type-errors result in broken
binaries (?)
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org
Reporter: heiko.le...@worldiety.de
CC: blitzrak...@gmail.com, dgre...@apple.com,

The following program compiles to a binary where the float is handled before
the int member. VC++ recognizes the error of print() taking rvalue references.
gcc yields the same result clang.
I think such errors should be caught. see https://gcc.godbolt.org/z/G4ddao
struct Test {
int m_x;
float m_y;
template<class Callable>
void withMembers(Callable&& callable) {
callable(m_x, m_y);
}
};
extern void print(int&&i);
extern void print(float&&i);
int notmain()
{
Test t{ .m_x=1, .m_y=2.0f};
t.withMembers([](const auto&... args){
( print(args), ...);
});
return t.m_x;
}
