Yes. That is one of the Fortran bugs, but there are more, see reference below.

I use CMake for a couple of Fortran projects, but Fortran is not used by the
CMake developers so it tends to be only weakly supported.  Thus, there are a
number of long-standing CMake fortran bugs you have to work around.  I
summarized those bugs (and the required workarounds) at
http://www.cmake.org/pipermail/cmake/2006-November/012052.html.  The
workarounds are pretty ugly (for example, change all occurrences of " use "
to "_use_" in your comment strings), but I do like CMake so I am willing
to put up with the Fortran workarounds for now, although it would be great
to get these CMake/Fortran bugs fixed instead.

Note, to see the full account of these bugs, you will have to create a new
bug tracker account, login to the new CMake bug tracker system and
explicitly jump to bugs 3109, 3144, or 3984.

Which brings up a general question to those in charge of the bug tracking
system: As a convenience to users can you make the bug tracker information
available in a read-only way which does not involve logging in?  I am well
aware you have had to recently fight off a spam attack, but if Mantis
is truly a secure system, it should be able to supply read-only information
about bugs without requiring an account, logging in, etc.
