Problem Converting Code Using std::vectors to MLIR #437

I am trying to compile a simple gather function using vectors for data storage using the compilation flag

cgeist $1 -O0 -g -fopenmp -S -o $fileBase.affine.mlir -I/usr/lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11 \
    -I/usr/lib/gcc/x86_64-linux-gnu/11/../../../../include/x86_64-linux-gnu/c++/11 \
    -I/usr/lib/gcc/x86_64-linux-gnu/11/../../../../include/c++/11/backward \
    -I/home/$USER_NAME/$PROJECT_NAME/build/lib/clang/18/include \
    -I/usr/local/include \
    -I/usr/include -D$4

The function that I'm trying to compile is

#include <iostream>
#include <vector>

#pragma scop
void gather_vec(std::vector<int> &a,
            std::vector<int> &b,
            std::vector<int> &idx) {
    for (size_t i = 0; i < idx.size(); ++i) {
        a[i] = b[idx[i]];
    }
}

int main() {
    std::vector<int> a; 
    std::vector<int> b = {1, 2, 3, 4};
    std::vector<int> idx = {3, 2, 1, 0};

    gather_vec(a, b, idx);

    // verification
    for (size_t i = 0; i < a.size(); ++i) {
        std::cout << "a[" << i << "] = " << a[i] << "\n";
    }

    return 0;
}

and when I run the cgeist command, I get some cleanup not handled and this error before printing out the intermediate MLIR. I have also attached the whole log.
