Bug ID: 95016
Summary: [DR 2082] Referring to parameters in unevaluated
operands of default arguments
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
We give two errors here:
void
f ()
{
int i;
extern void g(int x = i); // error
extern void h(int x = sizeof(i)); // OK
}
but [dcl.fct.default]/7 now says "A local variable cannot be odr-used
([basic.def.odr]) in a default argument."
