[cfe-dev] Type>>isObjCInterfaceType() blows up

[Emerson Murphy-Hill]

Ahoy!

I'm trying to determine the SourceLocation of an Objective-C instance  
variable's type, if there is one.  This seemed like a reasonable way  
to start:

     clang::ObjCIvarDecl* iVar = ... //your ivar here...
     clang::Type* t = iVar->getType().getTypePtr();
     t->isObjCInterfaceType();

Unfortunately, I get an EXC_BAD_ACCESS on the final line.  For the  
test case I'm working on, I would have expected it to simply return  
false, since my ivar is an int.

Thanks in advance,

Emerson
