Clang crashes when trying to capture a constant block in its own initializer. If clang can't handle this case, it should fail with a diagnostic instead of crashing only in assert builds. The crash goes away if `const` is removed.
```objc
#import <Foundation/Foundation.h>
NSUInteger bar(void (^captured)(void));
void foo()
{
// Remove "const" to fix the crash
__block const NSUInteger crashing_block = bar(^{
(void)crashing_block;
});
}
```
```
clang main.mm -c -fblocks -target arm64-apple-macosx -isysroot /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
```
