Bug ID: 41033
Summary: problem with _Atomic type determination and
compatibility for statement expressions - C mode
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: mib.bugzi...@gmail.com

I see this problem for expressions in initializatin, assignment, and parameter
passing, the test case is cut down from builds of open source applications like
ffmpeg and a couple others, using gcc8 stdatomic.h
Here's a test case
_Atomic(int) ai;
int fn1 ()
{
int j = ai; // This is OK
int i = ({ 1; ai;}); // This gets an error, initializing int with
incompatible type
// i = ai;
// i = ({ 1; ai;});
}
