Bug ID: 46668
Summary: Clang crashed when parsing destructor with parameter.
Assertion `(data().DefaultedDestructorIsDeleted ||
needsOverloadResolutionForDestructor()) && "destructor
should not be deleted"' failed
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend

Hi,all.
This code, bug.cc, with a small mistake, makes Clang-trunk crashed.
Interestingly, Clang-10 or Clang-9 handles this well with no crash. This is a
regression problem I guess.
$cat bug.cc
class a { ~a(int); };
class b: virtual a {};
$clang++ bug.cc
bug.cc:1:11: error: destructor cannot have any parameters
class a { ~a(int); };
^
clang-11:
/home/tuhaoxin/compilers/llvm-project/clang/include/clang/AST/DeclCXX.h:854:
void clang::CXXRecordDecl::setImplicitDestructorIsDeleted(): Assertion
`(data().DefaultedDestructorIsDeleted ||
needsOverloadResolutionForDestructor()) && "destructor should not be deleted"'
failed.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash
backtrace, preprocessed source, and associated run script.
