At revision 146606 the following code module vector_calculus intrinsic :: dot_product, sqrt
contains function len(r) real, dimension(:), intent(in) :: r real :: len len = sqrt(dot_product(r,r)) end function len end module vector_calculus end gives pr36192_mod_red.f90:12.26: end module vector_calculus 1 Internal Error at (1): write_symbol(): bad module symbol 'x' This code has been extracted from a larger one that did not give this error at revision 146282.
