Summary: crash in objc messaging
Product: clang
Version: unspecified
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: LLVM Codegen
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: daniel at zuster.org
CC: llvmbugs at cs.uiuc.edu
This test case (originally from PR4894) is still crashing:
--
ddunbar at ozzy:CodeGenObjC (master)$ cat t.m
typedef const struct objc_selector {
void *sel_id;
const char *sel_types;
} *SEL;
@interface I2
+(id) dictionary;
@end
@implementation I3;
+(void) initialize {
I2 *a0 = [I2 dictionary];
}
@end
ddunbar at ozzy:CodeGenObjC (master)$ clang -c t.m

interface declaration for 'I3'
