--- Comment #6 from Rogério de Souza Moraes <rogerio.souza at gmail dot com> ---
We got similar issue with a very small code using GCC v14.2:
https://godbolt.org/z/b5dqvnKqj
**********************
#include <vector>
void foo(int mod_id, std::vector<std::vector<int>> &_modMpcCluster) {
std::vector<int> cluster;
cluster.push_back(mod_id);
_modMpcCluster.push_back(cluster);
}
**********************
g++ -c -fpic -std=c++26 -O -DNDEBUG -Wall -Werror xxx.cpp
This returns the error:
```
