Bug Description

Binary package hint: gcc-4.4

When I compile the following program

program main
    implicit none
    ! Syntax error here
    write(advance='no') ' '
end program main

with gcc-4.4 on Ubuntu 9.10 using the following command

gfortran main.f90

, I get a segmentation fault. Complete GCC output:

f951: internal compiler error: Segmentation fault
Please submit a full bug report, with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.4/README.Bugs> for instructions.

Expected behaviour: gfortran raises an error.

Environment:

$ gcc -v
