Shoot. My bad there. Looks like the enumerator sentinel is missing. Will fix now. -Nathan On Wed, Jan 08, 2014 at 09:27:46PM -0800, Paul Hargrove wrote: >Ralph, >When rebuilding with --enable-debug and the original gcc-4.0.0 the SEGV >returns. >So, the ompi-1.4 in the LD_LIBRARY_

Ralph, When rebuilding with --enable-debug and the original gcc-4.0.0 the SEGV returns. So, the ompi-1.4 in the LD_LIBRARY_PATH was NOT the cause. Below is a backtrace from gdb which includes line numbers. The SEGV is in strlen() which suggests a string which lacks null-termination. The initial

Only takes <30 seconds of typing to start the test and I get email when it is done. Typing these emails takes more of my time than the actual testing does. -Paul On Wed, Jan 8, 2014 at 8:35 PM, Ralph Castain wrote: > If you have the time, it might be worth nailing it down. However, I'm > mindf

If you have the time, it might be worth nailing it down. However, I'm mindful of all the things you need to do, so please only if you have the time. Thanks Ralph On Jan 8, 2014, at 8:23 PM, Paul Hargrove wrote: > Ralph, > > Building with gcc-4.1.2 fixed the problem for me. I also removed an

Ralph, Building with gcc-4.1.2 fixed the problem for me. I also removed an old install of ompi-1.4 that was in LD_LIBRARY_PATH at build time and might have been a contributing factor. If I'd known earlier that it was there, I wouldn't have reported the problem without first removing it. I can b

Most likely problem is a bad backing store site - any chance you could give me a line number from this? There are a lot of calls to register params in that code and I'd need some help in figuring out which one wasn't right. On Jan 8, 2014, at 6:59 PM, Paul Hargrove wrote: > I am still testing

I am still testing the current 1.7.4rc tarball on my various systems. The latest failure (shown below) is a SEGV somewhere below MPI_Init on a old, but otherwise fairly normal, Linux/x86 (32-bit) system. $ /home/pcp1/phargrov/OMPI/openmpi-1.7-latest-linux-x86/INST/bin/mpirun -np 1 examples/ring_c
