[f2py] f2py and PGI again

[Berthold Höllmann]

I am having a hard time to get code compiled using PGI 7.0 to work
with f2py on linux_x86_64 and Python 2.5. I am aware of the
"sys.setdlopenflags(258)" trick from
<http://www.pgroup.com/userforum/viewtopic.php?t=345&postdays=0&postorder=asc&start=10&sid=84d954e1c5d2e4e7e87689253b9cb4de>,
but this trick leads to further segfaults::

  hoel at amur:20070327 cat aa20070327.f
        subroutine A()
  
        print *, "HALLO TEST"
  
        return
        end
  hoel at amur:20070327 f2py -c aa20070327.f
  ...
  hoel at amur:20070327 f2py -c aa20070327.f -m aa
  ...
  hoel at amur:20070327 python -c "import sys;sys.setdlopenflags(258);import untitled,aa;untitled.a();aa.a()"
  Segmentation fault (core dumped)
  hoel at amur:20070327 python -c "import untitled,aa;untitled.a();aa.a()"
   HALLO TEST
   HALLO TEST

There is not PGI involved up to this point. g77 is used to compile the
module, but without the "setdlopenflags" PGI compiled modules segfault
when they access e.g. the buildin for "write", something like::

  hoel at amur:20070327 f2py -c aa20070327.f -m aa  --fcompiler=pg --f77exec=pgf90
  ...
  hoel at amur:20070327 f2py -c aa20070327.f --fcompiler=pg --f77exec=pgf90
  ...
  hoel at amur:20070327 python -c "import untitled,aa;untitled.a();aa.a()"
   HALLO TEST
  PGFIO-F-202/list-directed write/unit=6/conflicting specifiers.
   File name = stdout     formatted, sequential access   record = 1
   In source file aa20070327.f, at line number 3
  hoel at amur:20070327 python -c "import sys;sys.setdlopenflags(258);import untitled,aa;untitled.a();aa.a()"
  Segmentation fault (core dumped)

How do I escape this catch-22?

Thanks
Berthold
