This looks like a simple omission. It's fairly uncommon to use the C99 _Bool
type (for which bool is a typedef), rather than the Objective-C BOOL type, in
Objective-C code. It shouldn't be too difficult to fix, I think we just need
an extra case in a couple of switch statements.

Hi,
the following simple program crashes because GSObjCSetVal in GSObjCRuntime.m
does not handle boolean values:
#import <Foundation/Foundation.h>
@interface TestObject : NSObject
@property (nonatomic, assign) bool switcher;
@end
@implementation TestObject
@end
int main(int argc, const char * argv[])
{
TestObject* test = [TestObject new];
[test setValue:[NSNumber numberWithBool:YES] forKey:@"switcher"];
return 0;
}
compiled with:
clang `gnustep-config --objc-flags` -x objective-c -fobjc-arc -std=gnu99
-fpascal-strings -fstrict-aliasing -lobjc -lgnustep-base `gnustep-config
--objc-libs` test.m
I think this is a serious defect. On my system the type that needed to be handled in
GSObjCSetVal would be "B16", but on other system this might be different.
I'm unsure about how a correct fix should be, so any opinions of people in the
know would be greatly appreciated.
Best regards,
Mathias
