Summary: jacobi.F90:90:0: internal compiler error: Segmentation fault Product: gcc Version: 4.6.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: kapi...@rz.rwth-aachen.de Created attachment 24713 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=24713 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 -PK
