I think this bug was already fixed when you filed the bug report. Still it would be great to have the test code from your github branch in base.

#import <Foundation/Foundation.h>

@interface A : NSObject
NSSize _s;
@implementation A
- (NSSize) s {
return self->_s;
- (void) setS: (NSSize) s {
self->_s = s;
int main() {
NSSize in = NSMakeSize(1.0, 2.0);
NSValue * v = [NSValue valueWithSize: in];
originally observed with:
NSValue * v = [NSValue valueWithBytes: &in
objCType: @encode(NSSize)];
A * a = [A new];
[a setValue: v
forKey: @"s"];

return 0;
