gfortran 4.0 series is seriously broken and shouldn't be considered for
production use. Indeed, your testcase and variations work with the gfortran 4.2
branch, except for the following:
$ cat a.f90
integer, dimension(3), parameter :: a=(/1,2,3/)
integer, dimension(3), parameter :: b=(/a(:)/)
end
$ gfortran a.f90
a.f90:0: internal compiler error: Segmentation fault
which is an ICE. Removing the "(:)" makes it work. The backtrace for the ICE
is:
Program received signal SIGSEGV, Segmentation fault.
