--- Comment #8 from Dominik Vogt <vogt at linux dot vnet.ibm.com> --- Some things to try with reduction-10.c: 1) Remove all OMP pragmas from the code. If it still fails it's not a limbgomp bug. 2) Replace "p7" in foo with just "7". If it still fails we know the bug is not triggered by the dynamic allocation of a or b.
