Summary: [4.5/4.6 Regression] Expected diagnostic "reference to
'type' is ambiguous" not given for function-local
static declaration
Product: gcc
Version: 4.5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: dev.lists@jessamine.co.uk
In g++ 4.5 and 4.6, a function-local static declared with an ambiguous type
does not yield the expected diagnostic. It appropriately fails to compile due
to a type not being resolved but doesn't give the user the root cause of the
failure as it did in 4.4.
Given the following code:
namespace N1 { typedef int T; }
namespace N2 { typedef float T; }
int main()
{
using namespace N1;
using namespace N2;
static T t;
}
4.4.5 outputs:
<stdin>: In function 'int main()':
<stdin>:9: error: reference to 'T' is ambiguous
<stdin>:2: error: candidates are: typedef float N2::T
<stdin>:1: error: typedef int N1::T
<stdin>:9: error: 'T' does not name a type
Both 4.5.0 (an old build I had lying around) and 4.6.0 (at rev 170646) output:
<stdin>: In function ‘int main()’:
<stdin>:9:14: error: ‘T’ does not name a type
If the static declaration and preceding using directives are moved to namespace
scope rather than being function-local, the expected diagnostic is output.
If the function-local declaration is made non-static, the expected diagnostic
is output.

This was broken by the fix for bug 35112. Any thoughts, Paolo?

Gosh, not really at the moment, quite a bit of time ago. Looks like, the whole
point of my changes was avoiding duplicate error messages, thus, worst case we
can re-instantiate the old logic, seems a better compromise?
