Hello, everyone. I have a strange problem. In my small app(i just traverse an<br>
AST), clang cannot parse expression:<br>
char* ptr = '\0';<br>
This nodes just dont appear in AST. Why clang ignored this statement or why<br>
it cant parse it? Character literal should just implicit cast to integral<br>
literal and then to null pointer.<br>
I've tried also test:<br>
char ch = '\0';<br>
this works good;<br>
I suggest, that the problem in DefinitionKinds.def or maybe similar, but i<br>
dont know what to do.<br>
<br>
