[Bug fortran/40638] RTE: "Unit number in I/O statement too large" -- fails with any low value

Sorry. In the middle of uploading the attachment I had a power cut! To respond
to your queries: Program and input file are now uploaded.

Yes it was compiled with 

gfortran -Wall testfile.f 

and no further options. I have found it necessary to use -static on some
installations but all of these compiles run fine. 

gfortran -v produces:

I should not be mixing libraries... this is a brand new installation on a new
machine (bought two weeks ago!). The gcc-4.3 collection were installed as part
of the initial SuSE installation. I only tried building gcc-4.4 after this
problem manifested. My build of gcc-4.4 was installed into /usr/local/ and the
only test I did was to substitute the gfortran executable (using a temporary
symlink) to compile the test program.

Thanks
