             Bug #: 51522
           Summary: ICE in gfortran 4.6.2, x86_64
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: adrian@llnl.gov


Created attachment 26066
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26066
this one is only reproducible when the modules are spread over multiple files

I accidentally created this ICE while I was delta-debugging Bug 51520; my
script was only testing for *any* Segmentation fault instead of a specific one
;-)

The machine is running Ubuntu 10.04, 64 bit on an Intel Xeon.

  gfortran -I. -O0  -c -o sidl.o sidl.f03 && \
  gfortran -O0  -c -o vect_Utils_type.o vect_Utils_type.f03 && \
  debugx f951 gfortran -O0  -c -o vectortest.o vectortest.f03
