This happened while executing user expression in lldb as record type was incorrectly received from dwarf. This assert will replace the infinite recursion with an error and will simplify further debugging of such cases. --- clang/lib/AST/RecordLayoutBuilder.cpp | 1 + 1 file changed, 1 insertion(+) diff --git a/clang/lib/AST/RecordLayoutBuilder.cpp b/clang/lib/AST/RecordLayoutBuilder.cpp index 6d819031cbef4..38618eefc5a87 100644 --- a/clang/lib/AST/RecordLayoutBuilder.cpp +++ b/clang/lib/AST/RecordLayoutBuilder.cpp @@ -187,6 +187,7 @@ void EmptySubobjectMap::ComputeEmptySubobjectSizes() { // Check the bases. for (const CXXBaseSpecifier &Base : Class->bases()) { const CXXRecordDecl *BaseDecl = Base.getType()->getAsCXXRecordDecl(); + assert(BaseDecl != Class && "Class cannot inherit from itself."); CharUnits EmptySize; const ASTRecordLayout &Layout = Context.getASTRecordLayout(BaseDecl); _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
