| Open demo.exe. Choose Fl_Menu. Click 'menubutton'. Now leave the widget, i.e. move the mouse outside the widget area (the popup menu is still visible). When now pressing the down arrow key FLTK crashes.
OS: Windows
FLTK: v.1.1.x_r5252
Compiler: gcc | |

| The bad news is that this also occurs in Linux rev 5221. The good new is that it occurs in Linux rev 5221, and thus there may be some hope of fixing it. | |

| An evil little bug. When the segfault occurs (FLTK 1.1 rev 5257, FC5, GCC4.1.1) in Fl_Menu's static routine, "forward()", there is some sort of event grab occuring. Subsequent events, including commands to GDB, are diverted into an event black hole, and the X server is effectively locked up. Ctl-Alt-Backspace, startx, cd <fltk>/test and you're ready for the next iteration.
Perhaps someone wiser can just look at the code and quickly diagnose the problem. I hope it's not yet another manifestation of the menu fix/refix/rerefix/... I stirred up six months or so ago! | |

| Fixed in Subversion repository.
Please verify with other applications. Please also test the right mouse button with popup menus. | |
