Hello all.
With the following system:
AMD 486 DX4100 with 20Mb RAM and Tseng ET4000W32i running
Linux 1.2.11 with XFree86 3.1.1
I have observed a problem with fvwm pre 2.0 pl 33 and pl 34, which do
not occur with fvwm 1.24 and twm.
With some programs e.g. Radiance (a ray tracer) whenever a window in
which the process is running is killed -- either by double clicking
on the "close button" or by giving the process a kill -kill
X hangs -- or more to the point fvwm hangs.
I think I have isolated the problem to 4 lines of code in the file
misc.c in the fvwm directory.
line 185 to line 188 in fvwm/misc.c:
if (Tmp_win->class.res_name && Tmp_win->class.res_name != NoName)
XFree ((char *)Tmp_win->class.res_name);
if (Tmp_win->class.res_class && Tmp_win->class.res_class != NoName)
XFree ((char *)Tmp_win->class.res_class);
A printf reveals that
Tmp_win->class.res_name is "NoName"
Tmp_win->class.res_calss is "NoClass"
NoName is "Untitled"
So it looks like fvwm tries to free something that is not "freeable"
I think that the problem lies in add_window.c line 129 to 135:
tmp_win->class = NoClass;
XGetClassHint(dpy, tmp_win->w, &tmp_win->class);
if (tmp_win->class.res_name == NULL) <----+
tmp_win->class.res_name = NoName; |
if (tmp_win->class.res_class == NULL) <----+
tmp_win->class.res_class = NoName; |
|
here is tmp_win->class.res_name "NoName" and
tmp_win->class.res_class is "NoClass".
The same or a related problem have been reported in pl 36 by Karl Eichwalder.
Yesterday I accidently send this message to fvwm-owner_at_hpc.uh.edu
Sorry!
