With the patch for PR 51578 (for GCC 4.7), the ICE is fixed. For the lines


integer(c_int) function vect_Utils_vuTriIneqHolds_c(u, v, tol, exception) &
use, intrinsic :: iso_c_binding
real(c_double) function vect_Utils_vuNorm_c(u, tol, badLevel, exception)
bind(c)
end function vect_Utils_vuNorm_c


one get the errors


   integer(c_int) function vect_Utils_vuTriIneqHolds_c(u, v, tol, exception)&
           1
Error: Parameter 'c_int' at (1) has not been declared or is a variable, which
does not reduce to a constant expression


   real(c_double) function vect_Utils_vuNorm_c(u, tol, badLevel, exception)
bind
        1
Error: Parameter 'c_double' at (1) has not been declared or is a variable,
which does not reduce to a constant expression


I think the second one is perfect - there is no "USE ISO_C_Binding" statement
in "function vect_Utils_vuNorm_c".


The first error is not that good as the problem is the "&" in
   function foo() &
     use m

A better error message would be a syntax error, pointing at the "&" - but I
think it is not really needed and also not easy to give a helpful message.

Hence, I close this PR as FIXED. If you think something else should be
improved, feel free to reopen this bug.


Thanks Adrian for reporting the internal compiler error.
