Re: [sigc] Segmentation fault with libsigc++ 2.0.3

[Martin Schulze <martin-ml hippogriff de>]

Hi Morten!

Thanks for reporting the bug!

However, please open a bug report at bugzilla.gnome.org to help us  
keeping track of it.
Please specify gtkmm2 as module since the error is most likely to be  
found there. It would be great if you appended a small-as-possible-but- 
compilable .cc test file. Obviously you are using a Glib::IOSource or  
something alike?

Regards,

 Martin
