This testcase is generated by a fuzzer.

Compiler Explorer: https://godbolt.org/z/GbhfEYor4

This valid code will crash on Clang Assertion Trunk:

void test() {
  (void) (__array_rank(int[10]) | 1);
}

It seems that this goes back to clang-3.0.

Stack dump:

clang++: /root/llvm-project/llvm/include/llvm/ADT/APInt.h:705: llvm::APInt& llvm::APInt::operator|=(const llvm::APInt&): Assertion `BitWidth == RHS.BitWidth && "Bit widths must be the same"' 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.
