Bug ID: 67777
Summary: unsigned wchar_t and signed wchar_t should cause
compiler errors but do not.
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: TrevorJamesHickey at gmail dot com
Target Milestone: ---
Is the following program valid C++?
void f(unsigned wchar_t){}
int main(){}
It compiles without errors.
The standard specifies that:
"signed or unsigned can be combined with char, long, short, or int."
wchar_t is a distinct type, but the standard makes no mention of it being able
to be qualified with signed or unsigned.
"Type wchar_t shall have the same size, signedness, and alignment requirements
(3.11) as one of the other integral types, called its underlying type."
Why can we add signed/unsigned qualifiers to wchar_t?
Is this by design? Can I get a warning about this?
