sure that a debugger can find them when stepping through code,
for example from the included testcase:
12 int test_it() {
13 c = 1;
14 d = 2;
-> 15 a = 4;
16 return (c == 1);
17 }
18
(lldb) p a
(int) $0 = 2
(lldb) p c
(int) $1 = 2
(lldb) p d
(int) $2 = 2
and a, c, d are all part of the file static anonymous union:
static union {
int c;
int d;
union {
int a;
};
struct {
int b;
};
};
Fixes PR19221.
