Reduced test case
I attach a case where clang wrongly reports uninitialized field in nested
struct.
------ field.c ------
typedef struct { double x, y; } NSPoint;
typedef struct { NSPoint origin; } NSRect;
static const NSPoint NSZeroPoint = { 0, 0 };
double test(void) {
NSRect frame = { NSZeroPoint };
return frame.origin.x;
}
---------------------
$ clang --analyze field.c
field.c:8:2: warning: Undefined or garbage value returned to caller
return frame.origin.x;
^ ~~~~~~~~~~~~~~
1 warning generated.
