I have the following class:
#import "BugTest.h"
#ifdef MAKE_BUG_DISAPPEAR2
static const unsigned int kArraySize = 22;
#else
static unsigned int kArraySize = 22;
#endif
@implementation BugTest
- (void)aBug;
{
NSUInteger bbb[kArraySize] ;
#ifdef MAKE_BUG_DISAPPEAR1
for( NSUInteger i = 0; i < MAKE_BUG_DISAPPEAR1; i++ ) bbb[i] =
0;
#endif
for( NSUInteger i = 0; i < kArraySize; i++ ) bbb[i] = 0;
for( NSUInteger i = 0; i < kArraySize; i++ )
{
fprintf(stderr, "a[%lu] = %lu\n", (unsigned long)i, (unsigned
long)bbb[i]); // <--- Pass-by-value argument in function call is
undefined
};
}
@end
The Static Analyzer says: " Pass-by-value argument in function call is
undefined", which I just plainly do not understand.
Why does this error message go away when I add:
#define MAKE_BUG_DISAPPEAR1 3
Why does it NOT go away with:
#define MAKE_BUG_DISAPPEAR1 2 // or anything less than 3 ? What is so
magical about 3?
Why does this error message go away when I add:
#define MAKE_BUG_DISAPPEAR2
Is this correct Objective-C or not?
Kind regards,
Gerriet.
