Tobias -- I'm able to replicate the problem with 1.8.4 and 1.8.8 and 1.10.0 on OS X 10.10.5 (Yosemite) and Xcode 7.0.1. I'd suggest filing a bug at bugreporter.apple.com with the information that clang provided in their output.
If there's a bug in the compiler, there's not much that we here at OMPI can do without digging in deep to understand the actual bug (not just one of its symptoms/manifestations) and then putting in a workaround. We've been a bit resistant to putting in compiler workarounds in the past, because that would be a nightmare (since Open MPI supports so many compilers). Instead, we've encouraged compiler vendors to fix their compilers. > On Oct 20, 2015, at 7:07 AM, Tobias Hilbrich <tobias.hilbr...@tu-dresden.de> > wrote: > > Hi Gilles, > > as for that, recompiling OpenMPI works, but causes no change here. > > -Tobias > > -- > Dr.-Ing.
