Created attachment 25037
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25037
Fortran source files to show the bug.

A namelist read of the file 

$indata
NFP = 5,
!  
!

results in:
Fortran runtime error: Cannot match namelist object name !

I have produced the error with gcc 4.6.0:
gfortran -v
Using built-in specs.

I'm sorry, I rely on others to install compilers, so I can't test it on other
versions.

This seems very similar to Bug 49791

Attached is a short code which produces the error.
