--- Comment #5 from Anton Shterenlikht <mexas at bristol dot ac.uk> ---
I get the same error:

caf -c -O2 -Wall -fPIC -g -fbacktrace -fall-intrinsics
-fcheck-array-temporaries -fopenmp -I/usr/local/include cgca_m3pfem.f90
cgca_m3pfem.f90:1407:0:

 end module cgca_m3pfem

internal compiler error: in gfc_conv_descriptor_token, at

GNU Fortran (FreeBSD Ports Collection) 7.3.0

I think this is a regression from 7.2 to 7.3.

This was building ok a couple weeks ago with 7.2.

It will take me a while to narrow down the problem code.
