FW: SetIcon in sample programs causing BadAlloc error in gdk (wx2.8.3, SunStudio12, g++ 3.4.3)

[Bond, Gary D]

Vadim,

Thanks for your reply.  I caught the minimal sample in the debugger and
it is failing at the same location.  In the wxBitmap::GetPixbuf method.
In answer to your question Does GetPixbuf return anything valid, the
answer is it never returns from GetPixbuf.  The gtk error is triggered
in the GetPixbuf method where it is calling the
gdk_pixbuf_get_from_drawable on line 937 of src/gtk/bitmap.cpp.  The
gdk_pixbuf_get_from_drawable function is passed
M_BMPDATA->m_mask->GetBitmap(), width and height, with all other
arguments 0.  The width and height values are both 32.  So it would seem
as though the mask might be a problem???

When I run the minimal program I get the following error:

The program 'minimal' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
	(Details: serial 141 error_code 11 request_code 131 minor_code
5)

To generate the backtrace given in the earlier email I did use sync when
I ran the executable in the debugger (dbx).

Thanks for your assistance.  I'll try to find out what it will take to
upgrade to 2.8.7.  Unfortunately, it sometimes takes a miracle to do the
simplest things around here.

Thanks again,
Gary

 First of all you should really use wx 2.8.7, it's 100% compatible with
2.8.3 so you shouldn't have any trouble upgrading to it but it contains
many bug fixes and while I don't remember anything related to this one,
you
should still try it first.

 So in the minimal sample too?

 Just to confirm it, did you run it with --sync command line option?

 Can you check if GetPixbuf() returns something valid (at least non
NULL)?

 It's really difficult to do anything about such bug without being able
to
reproduce it or even see the details of the stack trace... Does the bug
appear only when using some visuals by chance? Which one do you use in
fact?
