Clang crashes while compiling my project #72880

Open ogigato opened 12 months ago

ogigato commented 12 months ago

CLang version: 16.0.5, using MSVC-like command line. This project compiles ok using MSVC compiler, with the same arguments.

I can't seem to open the zip file.

ogigato commented 11 months ago

Hi, thank you for your interest. Tomorrow morning I will upload a new zip file. Perhaps it fails because I used 7-zip and deflate64 as compression algorithm.

Regards, Óscar.

Hi shafik, I have updated the zip file. I hope you can open it now.

BRs.

Confirmed in Clang 17 and post-18 trunk: https://godbolt.org/z/81qnjez5o Reduced by me and C-Reduce:

struct stChildParam {};

struct RegParam : stChildParam {
  int count = 0;
};

template <typename _TFC>
struct DataGather {
  void AddParameters() {
    RegParam regPar = static_cast<RegParam>(stChildParam{});
  }
};

void f() {
  DataGather<int>{}.AddParameters();
}

Backtrace:

clang++: /root/llvm-project/clang/include/clang/AST/Type.h:753:
const clang::ExtQualsTypeCommonBase* clang::QualType::getCommonPtr() const:
Assertion `!isNull() && "Cannot retrieve a NULL type pointer"' failed.

PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
