Bug ID: 113653
Summary: Failure to diagnose use of (non-constant-expr) const
objects in static initializers
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: bugdal at aerifal dot cx
Target Milestone: ---
The following is a constraint violation:
int foo()
{
static const int x = 1;
static const int y = x; // not a constant expression
return y;
}
However, gcc does not diagnose it as such, even with -Wall -Wextra.
This appears to have been a regression somewhere between the gcc 4 era and now.
I'm not sure what component this should be assigned to. I chose "c" because
it's C-specific that this is not a constant expression; it would be in C++.
