[Inkscape-devel] Glib::ustring.c_str() corrupted on the heap [was: Remaining critical bugs for 0.45]

Kees Cook spiegò:

With some help from mental, this is now fixed. General warning about using the .c_str() function on Glib::ustring's returned from objects: don't use 'em: they can get trashed on the heap. Instead, use a local Glib::ustring, and call it's .c_str() when you need it.

e.g.

No: char * str = Node->contents().c_str(); do_something( str );

Yes: Glib::ustring str = Node->contents(); do_something( str.c_str() );

Just curious: any idea why?
