the reproducer (MPI needed)

Hi, 
the 4.6.1 (and 4.6.0) versions of gfortran compiler suffers from a SIGSEGV if
compiling the attached Fortran code jacobi.F90. 

The bug does NOT apper with  4.5.1 version of gfortran. 

The error hangs together with the -finstrument-functions option.

Since the attached code snippets are MPI programs, you need a version of e.g.
OpenMPI (we use 1.4.3).

Best wishes
