Hi guys
I’m having problems with a Fortran based code that I develop with
OpenMPI 3.0.0 on Mac OS X. The problem shows itself with both gfortran
and intel ifort compilers, and it runs perfectly with version 2.1.2 (and
earlier versions).
Launching the code, even without using mpiexec, causes a segfault when
my code calls mpi_init()
Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.
Backtrace for this error:
#0 0x1107a41fc
(…)
#10 0x10f86eff1
Segmentation fault: 11
Recompiling OpenMPI with —enable-debug, and launching the code through
lldb gives:
(lldb) run

Any thoughts?
