Steps to Reproduce:

1. input this code:

#include <vector>

std::vector<uint64_t> test(1 << 22);

int main() {
  for (int i = 0; i < (1 << 22); i++) {
    test[i] = i;
  }
  while (true) {
    switch (test[0] % 4) {
      case 0:
        test[0] = test[0] * 0x5deece66d + 0xb;
        break;
      case 1:
        test[0] = test[0] * 0x5deece66d + 0xb;
        break;
      case 2:
        test[0] = test[0] * 0x5deece66d + 0xb;
        break;
      case 3:
        test[0] = test[0] * 0x5deece66d + 0xb;
        break;
    }
  }
  return 0;
}

The C++ grammar (which has been frozen in eb03486, so don't hold your breath waiting for a fix for this, unless #50140 actually lands this month + an alternative grammar for C++ is found) does not like your 1 << 22 used when defining the vector. Use a define or extra parenthesis to work around that..

std::vector<uint64_t> test((1<<22));

Thanks for the analysis @alexandruavadanii, you are correct.

Nonetheless, I've opened jeff-hykin/better-cpp-syntax#654 in the upstream repo. There's some chance that the owner of the repo there changes the license back at some point.
