Dear Fred,
I would say that you're using a buggy gfortran version
(http://lists.debian.org/debian-gcc/2009/03/msg00070.html). You may
want to check your version with 'gfortran --version' in order to be
sure of it. The '-malign-double' switch provides only a slight
optimization and as you have
Hi Jon,
Thanks for the feedback. The version I am using (which is not that
reported in the web page you mention, Version: 4:4.3.2-2) is:
GNU Fortran (GCC) 4.4.6 20120305 (Red Hat 4.4.6-4).
Hence it appears that the bug hasn't been entirely dealt with. Ian
Tickle was getting segmentation
I'm using gcc 4.7.2 (latest stable version I think). I don't get the
compilation error of the FORMAT statement but I do get the segfault error
on running with the '-malign-double' switch that I reported. So it would
appear that even the current stable version is buggy! As Jon said the
Hi Fred
If you look very carefully at your Fortran code you will probably
find a small error/inconsistency that g77 allowed but gfortran picked
up on or compiled as written rather than as intended. My move from
g77 to gfortran when building Mosflm (which is moderately large) was
pretty
Hi Fred
I regularly compile F77 code with gfortran: I always get lots of warnings
and the occasional error that I didn't get with g77 mainly because gfortran
is much stricter applying the standard (and a good thing too!). I also
regularly use ifort (which isn't quite as strict as gfortran and

Dear all,
By popular request here is an example of some code where gfortran gives
run time errors. This is at the very beginning of the program, the first
write statement where a parenthesis is seen as missing at run time: (the
first hyphens are not within the Fortran code but there to

The relevant bit of code, with the FORMAT statement closed with a ')' and
an END statement added to make it a viable program, is:
WRITE (*,10)
10 FORMAT(///,25X,'*',
. /,25X,'* *')
END
For me this compiles
Hi,
The command:
$ aptitude install fort77
would install an f77 command on Ubuntu/Debian Linux.
In fact that's a wrapper for f2c, but maybe it behaves like
a real f77 compiler, I would give it a try personnally.
