I installed wxX11 development environmnt on Ubuntu+VMWare
and I built a wxWidget sample program named "dialogs" at first.
build was normally ended.

and when started the binary of "dialogs",
it stopped showing the message
"**** GLib-GObject-WARNING invalid cast PangoXFont to PangoFcFont"
and immediately "SIGSEGV segmentation fault" had happened.

wxX11 configure parameters are the followings.

--enable-debug
--with-x11
--enable-log
--with-opengl
--enable-unicode //not default ?
--disable-shared //not default
--enable-threads // default

and pango library is

libpango1.0-0-dbg 1.20.5-0ubuntu1.1
libpango1.0-dev 1.20.5-0ubuntu1.1
libpango1.0-doc 1.20.5-0ubuntu1.1

-------------

the cause of SIGSEGV segmentation fault might linked to
"invalid cast warning"

How to dissolve the problem ?

thanks
