Hello world,

the attached patch was committed as obvious as rev. 167416.  I mentioned
the PR in the changelog because that was the test case I found the bug
in.

2010-12-03  Thomas Koenig  <tkoenig@gcc.gnu.org>

	PR fortran/44352
	* dump-parse-tree.c (show_symbol):  Don't show formal namespace
	for statement functions in order to avoid infinite recursion.
