[Patch, fortran] PR29641 [4.1/4.2/4.3 regression] ICE in gfc_get_derived_type

["Paul Richard Thomas" <paul dot richard dot thomas at gmail dot com>]

:ADDPATCH fortran:

Jakub Jelinek posted this rather embarrassing PR - in spite of all the
testing a month ago, the rather simple testcase, attached, causes an
ICE because the derived type does not have a proc_name.  The fix is
utterly trivial - bail out with a NULL namespace if there is no parent
to search.  The testcase is the reporters, with the addition of a main
programme. Whilst the test is dg-do compile, the programme does run to
test functionality, if needed.

Regtested on Cygwin_NT/PIV - I intend to commit this tomorrow morning
under the obvious rule unless I receive any objections.  I will have
to follow it in a few days with commits to 4.2 and 4.1, since I
temporarily do not have anything other than trunk.  The same goes for
a couple of okayed patches that I will commit tomorrow.

Best regards

Paul
