I have installed g95 in ubuntu hardy heron 64 bit. However, when I try to compile a program that writes a simple one line statement, I end up getting an error:

jpm@joe-tablet:~/Desktop$ g95 test.f90
/tmp/ccM9RsRT.s: Assembler messages:
/tmp/ccM9RsRT.s:9: Error: suffix or operands invalid for `push'

What do I need to do to compile programs without this error? Thanks.
