Source file which triggers the internal compiler error

Trying to allocate a derived type component, which is a deferred length
character variable, causes gfortran (GNU Fortran (GCC) 5.0.0 20140831
(experimental)) throwing the following internal compiler error:

[507]> gfortran m_strings.f90
m_strings.f90:38:0: 

       allocate(character(newsize) :: s%chars)
