That's right two occured in function
static void paint_menu(
MenuRoot *mr, XEvent *pevent, FvwmWindow *fw)
[line 4056 im menus.c]
one in line 4063:
int bw = MST_BORDER_WIDTH(mr);
another in line 4117:
if ((MST_FACE(mr).type != SolidMenu &&
MST_FACE(mr).type != SimpleMenu &&
!MST_HAS_MENU_CSET(mr)) ||
In both cases *mr is involved. I am quite sure that I checked if the
pointer mr or its subpointers were NULL before accessing it to prevent
the seg fault. This check was passed but the seg fault did still
occur. Maybe one of the pointer is not NULL but points to an invalid
segment (However this can happen). I will do a double check of this
test tonight or tommorow.
The third one occured in another function in menus.c. Unfortunately I
can't remember where it was. Maybe it happens again.
