for (Decl *D : MostRecentTU->decls()) {
auto *ND = dyn_cast<NamedDecl>(D);
if (!ND)
continue;
// Check if we need to clean up the IdResolver chain.
if (ND->getDeclName().getFETokenInfo() && !D->getLangOpts().ObjC &&
!D->getLangOpts().CPlusPlus)
S.IdResolver.RemoveDecl(ND);
}
ND->getDeclName() returns ND->Name, which is 0. Then getFETokenInfo is called without check.
It can happens when compile failed(clang::interpreter will CleanUpPTU automatically) or manually undo by user.
