// Tests the ChainedConsumer's ability to recover from errors. .x produces 
// #include \"CannotDotX.h\" \n void wrapper() {CannotDotX();}, which causes
// a TagDecl to be passed trough the consumers. This TagDecl is caught twice by
// the ChainedConsumer and cached is the queue of incoming declaration twice.
// If we encounter error the ChainedConsumer shouldn't try to remove the 
// declaration twice and this test makes sure of that.

 // Uses a bug in the implementation of .L, which must be fixed soon.
 // Exposes another issue with the VerifyDiagnosticConsumer in the context of

 // preprocessor most probably we lose track of the errors source locations
 // and files.
