Subject: xdvi problem
Content-Type: text/plain; charset=us-ascii
Mime-Version: 1.0
I compiled xdvi on a SGI Indy (R4400) running IRIX 5.2 and X11R5.
It compiled fine, but when I run the program it seg faults as soon as
the window is exposed. I traced down the problem to the XtDispatchEvent()
call on line 1244 in events.c. This call is made several times with
various types of events, but on an Expose event I get the following
error in dbx:
Process 29121 (xdvi) Segmentation fault (Signal 11) [XMapWindow:23 ,0xf776d98]
The event structure looks normal, although I'm not really sure what it
is supposed to contain. On the last event that succeeds (a MapNotify), the
structure contains:
union _XEvent {
type = 19
xmap = struct .41fake {
type = 19
serial = 75
send_event = 0
display = 0x10011868
event = 83886096
window = 83886096
override_redirect = 0
}
}
And during the Expose event on which it fails, the structure contains:
union _XEvent {
type = 12
xexpose = struct .34fake {
type = 12
serial = 75
send_event = 0
display = 0x10011868
window = 83886101
x = 0
y = 0
width = 14
height = 984
count = 0
}
}
... the only thing that seems odd to me is that the width is 14. Maybe it's
the scrollbar?? And the window number is different that the window number
for the previous event. I don't know enough about X to know if this is
normal or not.
Anybody have any clue what's going on?? I'm stuck.
Thanks in advance,
Bill
