Hallo,
well,
it works better if one comments in
wxwidgets.cpp
      // wxPLGetApp().RemoveFrame( dev->m_frame );
in that the window does not close, but the application
does not segfault anymore.
In test.c, plplot opens another window correctly and
the first window becomes responsive again (why?).

My explanation is (but I know nothing about wxwidgets)
window does not close because of a process owning it
(some thread?). If the resources of the window are
freed, the segmentation fault follows probably as soon
as the thread tries to access them (the thread might be
some event loop?).

Fulvio
