File test.f90 gives the internal compile error

I'm using: GNU Fortran (Gentoo 4.6.1-r1 p1.0, pie-0.4.5) 4.6.1
Compilation flags are: -march=native -funroll-loops -pipe \
 -ftree-vectorize -floop-strip-mine \
 -floop-block -fimplicit-none -finit-real=NAN -ggdb

In addition to the internal compiler error, there is a problem mentioned in a
comment.  According to a Fortran language lawyer, Fortran 2008 allows two local
definitions of procedures to have the same binding label.  This problem is
illustrated in a comment.  I'm mainly filing this bug because of the internal
compiler error, which reads as follows:

 test.f90: In function 'test':
test.f90:11:0: internal compiler error: in gimplify_expr, at gimplify.c:7477
Please submit a full bug report,
with preprocessed source if appropriate.

My CPU is: Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz

Thanks,
