https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225229 Bug ID: 225229 Summary: hwloc broken on 11.1-RELEASE Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: jwb@freebsd.org hwloc-info and other hwloc binaries crash on startup on 11.1-RELEASE. This problem also causes slurmd to crash. It occurs consistently on some machines and in some cases not on an identical machine. This issue is probably the root cause of the following openmpi issue: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=221946 1.11.1 seems to work fine. I have not tried anything between 1.11.1 and 1.11.7, but the openmpi PR below suggests 1.11.3 as the cutoff. We might want to consider rolling back to that version until the root cause is determined. Compiling with -O0 helps on some systems, but not others. -O1 also helps on some systems. Upstream developer suggested a clang bug. It seems unlikely to me that a code generator bug of this sort could go undetected this long, but given the unusual things hwloc does, it should be considered a possibility. https://github.com/open-mpi/hwloc/issues/282#issuecomment-357539630 Compiling with gcc seems to help, but that may only mean that gcc arranges variables in a different way that prevents an hwloc bug from causing critical corruption. -- You are receiving this mail because: You are the assignee for the bug.home | help
