<pre>Problem
=============
While parsing this simple file with openmp flags passed to the compiler,
frontend crashes (as it says) due to a segmentation fault.
The code is a very toned down version of one of our project files, so excuse
the absolute paths and long compile command.
To get the crash, open the zip, compile the main.mm file using the command
written below.
crash is in 2b510dd7e3c176926c36af1e83f3f033d55b1935 as well as release 11
Compile Command
===========
clang -Xclang -fopenmp
-F/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/System/Library/Frameworks
-isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
main.mm
Code
============
```
#include
"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/AppKit.framework/Versions/C/Headers/NSWindow.h"
#include
"/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/objc/NSObject.h"
class Foo {
int a;
};
@interface Bar : NSObject <NSWindowDelegate> {
Foo *foo;
}
- (void)setSystemAndWindowCocoa:(class Foo *)foo_1;
@end
@implementation Bar : NSObject
- (void)setSystemAndWindowCocoa:(Foo *)foo_1 {
foo = foo_1;
}
@end
```
