Bug ID: 86351
Summary: Array references as arguments to ternary operator
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: Simon.Richter at hogyros dot de
Target Milestone: ---
The code
char const array1[2] = { 'a', 'b' };
char const array2[2] = { 'c', 'd' };
char foo(bool b) {
char const (&bar)[2] = b ? array1 : array2;
return bar[1];
}
is accepted by g++ and rejected by MSVC.
My interpretation of the standard would be that MSVC is correct here, as the
array decays into a pointer in the ternary operator, but it seems gcc's
ternary-as-lvalue extension will also pass array types through ternaries if
they are both the same.
- Is this intentional?
- Will it remain supported?
- Can it be turned off somehow?
