--- Begin Message ---Package: g++ Version: 4:9.2.1-3 When executing code compiled with g++ 9.2.1 that has OpenMP for-loops with vectors as shared variables, it results in a segmentation fault. According to Asan (address sanitizer), this might be due to double- freed variables when running the code. Example: #pragma omp parallel for schedule(static) num_threads(nthreads) shared(some_vector, some_variable) for (int i = 0; i < some_vector.size(); i++) { some_func(some_vector[i], some_variable) } Setup: - Processor Ryzen 2700 (8 cores) - Kernel version 5.2+106 - Compile flags tried: -std=c++11 -fopenmp -march=native -O2 The version currently in buster (4:8.3.0-1) and older do not show this problem. Tried with different samples of code in different projects and they all presented the same issue. Potential problems such as out-of- bounds writes were already discarded. Compiling without OpenMP does not produce such error.
