llvm dev - Jun 2012 - [LLVMdev] Have you guys met this issue about "typeinfo" & "vtable" of, ASTConsumer and PluginASTAction?

Hello Guys,

From this morning, I have been always trying PrintFunctionNames - an example of
clang, but during compiling I was always meeting
"__ZTIN5clang15PluginASTActionE", referenced from:
__ZTI24PrintFunctionNamesAction in PrintFunctionNames.cpp.o.

In fact, I didn't have "__ZTIN5clang15PluginASTActionE" in the
symbol table, only I have was "__ZTVN5clang15PluginASTActionE".

So, could you tell me what's going on and how to fix it?Thanks,Jeffrey.
