Crash upon semantic analysis C++ code #104800

Open lopippo opened 3 weeks ago

lopippo commented 3 weeks ago

Greetings,

I use Clang as a semantic analyzer in the KDevelop IDE. There are files that make it crash. I researched the problem using 'strace kdevelop' and found that the Clang analyzer was crashing. Then I reconstructed the command line for the analysis of the culprit file and ran that command in the terminal. As per the instructions in the output of the program upon the crash, this is the crash stack (I also attach two diagnostic files, see the end):

Greetings, I use Clang as a semantic analyzer in the KDevelop IDE. There are files that make it crash. I researched the problem using 'strace kdevelop' and found that the Clang analyzer was crashing. Then I reconstructed the command line for the analysis of the culprit file and ran that command in the terminal. As per the instructions in the output of the program upon the crash, this is the crash stack (I also attach two diagnostic files, see the end): ``` 0.

Could you please try 19 or main branch?

Could you please try 19 or main branch?

Yes, I'll try to first compile the suite and then check.

One observation that I made right at the moment (do not know if that is useful) is that clangd can parse and check successfully that specific file:

Greetings, sad to say that the crash still occurs with main branch of git repo cloned today: See the attached terminal-output.txt file. Added both diagnostic files as in my first issue post. diagnostic-cpp-hpp-files.zip

Most sincerely, Filippo

Endilll commented 3 weeks ago

You can try to ask about new diagnostics that clangd gives you in #clangd channel on our Discord server. Let's keep this issue for the crash you reported.

Fine, thank your for your responsivenes :-) I deleted my comment above, which looked out-of-context.

[ EDIT ] I have built the whole software again (something must have failed in my first trial) and clangd works flawlessly. I confirm, however, the issue as reported initially.

Most sincerely, Filippo

Endilll commented 3 weeks ago

Confirmed on Clang 20.0: https://godbolt.org/z/vKeEKMEjT Reduced by me and C-Reduce:

struct Ponderable {
  void operator==(Ponderable);
};

struct PolChemDefEntity {
  void operator==(PolChemDefEntity);
};

struct Sequence {
  void operator==(Sequence);
};

struct Ionizable : PolChemDefEntity, Ponderable {
  using PolChemDefEntity::operator==;
  using Ponderable::operator==;
};

struct Polymer : Sequence, Ionizable {};

using T = decltype(Polymer{} == Polymer{});

Clang 20.0 crash:

clang++: /root/llvm-project/llvm/include/llvm/Support/Casting.h:578:
decltype(auto) llvm::cast(From*) [with To = clang::CXXMethodDecl; From = clang::NamedDecl]:
Assertion `isa<To>(Val) && "cast<Ty>() argument of incompatible type!"' failed.

Greetings, I use Clang as a semantic analyzer in the KDevelop IDE. There are files that make it crash. I researched the problem using 'strace kdevelop' and found that the Clang analyzer was crashing. Then I reconstructed the command line for the analysis of the culprit file and ran that command in the terminal. As per the instructions in the output of the program upon the crash, this is the crash stack (I also attach two diagnostic files, see the end): ``` 0.

Greetings, I use Clang as a semantic analyzer in the KDevelop IDE. There are files that make it crash. I researched the problem using 'strace kdevelop' and found that the Clang analyzer was crashing. Then I reconstructed the command line for the analysis of the culprit file and ran that command in the terminal. As per the instructions in the output of the program upon the crash, this is the crash stack (I also attach two diagnostic files, see the end): ``` 0.
