problem with 4.2rc2 and wxt_gui.cpp on Solaris

[Kostas O. <ko...@re...>]

Hello,

I just built 4.2rc2 on Solaris 10 using Sun's compilers (Sun 
Studio 11).  Everything seems to work, but when I press the 
"Configuration" button on the wxt terminal, I get a core dump.

This is what happens:

(<unknown>:9638): Gtk-CRITICAL **: file gtklabel.c: line 
2643: assertion `str != NULL' failed
(<unknown>:9638): Gtk-CRITICAL **: file gtklabel.c: line 
2643: assertion `str != NULL' failed
(<unknown>:9638): Gtk-CRITICAL **: file gtklabel.c: line 
2643: assertion `str != NULL' failed
(<unknown>:9638): Gtk-CRITICAL **: file gtkaccellabel.c: 
line 187: assertion `string != NULL' failed
(<unknown>:9638): Gtk-CRITICAL **: file gtkmisc.c: line 185: 
assertion `GTK_IS_MISC (misc)' failed
(<unknown>:9638): Gtk-CRITICAL **: file gtkcontainer.c: line 
946: assertion `GTK_IS_WIDGET (widget)' failed
(<unknown>:9638): Gtk-CRITICAL **: file gtkaccellabel.c: 
line 384: assertion `GTK_IS_ACCEL_LABEL (accel_label)' failed
Segmentation Fault (core dumped)


I found out that the first 3 messages are caused by

	wxCheckBox *check1 = new wxCheckBox ( ...)

in wxt_gui.cpp.  But I have no idea what to do to fix them. 
  I have wxwidgets 2.7.2.

Any help would be appreciated.

Hi Kostas,

Thanks for taking some time to build gnuplot and test new features.

I have several remarks regarding your problem:
First, wxWidgets 2.7.2 is a "development" version. It should be safer to=20
use either the 2.6.3 or 2.8.0 versions which are "stable".
Then, it could be also a bug in the gtk, although it seems less probable.
FInally, you could help us by providing the backtrace corresponding to=20
the core dump. It will give us some idea of where the segmentation fault=20
is coming from. If you need some help to do this, don't hesitate to ask.

Best regards,
