Re: wired problem with Gtk::FileChooserDialog

[VLG <3rdshift comcast net>]

Alexander,

if nothing else works, try running your program with valgrind - you are
clearly
experiencing *out of bound write* error.

If that doesn't work. surround your FileChooserDialog var with 4K
buffers
before and after the var declaration. Fill the buffer with say 'a's and
'b's
and then examine the content after the crash.
