rdapp at linux dot vnet.ibm.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rdapp at linux dot vnet.ibm.com --- Comment #12 from rdapp at linux dot vnet.ibm.com --- (Writing from a colleagues machine ...) Thinking about it, I'm quite sure the dynamic allocation must come from here: > #pragma omp parallel for reduction(*:y[:p4]) reduction(|:a[:p5]) ^^^^^^ ^^^^^^ I.e. the bug should go awaz if you replace either p4 or p5 or both with the numeric values.
