So that may be related = to the bug you mentioned. I do get occasional good core dumps, as noted above. At this time I cannot = run stable to patch the core dump issue. I did however install clang3.6. I have rebuilt the ports we are seeing prob= lems with against that just to rule it out. That is however, very unlikely.=20 I will continue to gather more dumps if they produce valid cores. If there = is a patch I can rebuild against that fixes the "error 14" issue, I'll give is a whirl. --=20 You are receiving this mail because: You are the assignee for the bug.=
