[STR New] Link: http://www.fltk.org/str.php?L2836 Version: 1.3-current When calling Fl_Window::copy_label() with the *current* label as argument e.g. Fl_Window win; win->copy_label( win->label() ); it is possible to get memory corruption due to current implementation, that first free()'s the existing label() - which is the same adress as the argument - then sets the label with the now possibly corrupted argument. (I know it is not very usefull to make such a call, but this is only the stripped down essence of a bug I hunted down in a more complex app, where things are not so obvious) On my system (Ubuntu 11.10) the corruption happens with certainty, don't know if it would be the same on other systems. Fix is very easy: Just make the strdup() before the free()! The said is also true for Fl_Widget::copy_label(). Attached a fix, a test program and a screenshot of the corrupted window title after executing the test.
