<pre>Test case (prog.c):
int main()
{
(_Atomic int)0;
}
Compilation command line:
clang prog.c -Wall -Wextra -std=c11 -pedantic-errors
Observed beaviour:
The following error message was outputed:
error: used type '_Atomic(int)' where arithmetic or pointer type is
required
Expected behaviour:
No error message outputed.
The program is well-formed.
_Atomic qualification of the scalar type int is allowed here.
See 6.5.4/2:
"Unless the type name specifies a void type, the type name shall
specify atomic, qualified, or unqualified scalar type, and the operand
shall have scalar type."
Note:
GCC accepts the program without outputing any error message.</pre>
