About a month ago, I posted a message of which this is a synopsis: > Environment: Sun 4/40 (IPC), SunOS 4.1 > MIT X11R4 (patch level 18) server > window manager: OpenWindows 2.0 olwm << OR >> X11R4(18) twm > compilation of X11R4 with Sun's bundled cc > > The client /usr/openwin/bin/xview/mailtool sometimes crashes the > server. The problem occurs when deleting the message at the end of the > list of messages. It looks as if the window containing the message > headings is extended to the bottom of the screen (overwriting all other > windows, including the window manager's decorations). From dbx: > > program terminated by signal SEGV (no mapping at the fault address) > (dbx) where > cfbFillBoxSolid() at 0x10e44 > cfbPaintWindow() at 0x7e34 > miSpritePaintWindowBackground() at 0x925c0 > miHandleExposures() at 0x88d08 > cfbCopyArea() at 0xc1d8 > miSpriteCopyArea() at 0x933ac > ProcCopyArea() at 0x2bb98 > Dispatch() at 0x29300 > main() at 0x3ae04 I got a response from Fred Romelfanger <uunet!stsci.edu!fred> who reported in part: > I run X11R4 (p18) built with Sun C 1.0 on a SS1+ GX.

The only real difference I see is that I am also using the > xview libraries compiled from source. I got responses from the following people using slightly different environments, but all OW mailtool on MIT X11R4 server, to report the same problem with no solution: > ytliu@ee.nthu.edu.tw (Yuan-Der Liu) > National Tsing Hua University > Department of Electrical Engineering > Hsinchu, Taiwan, ROC > > Francois Staes > Origin/Technology Support > Eindhoven, The Netherlands. > uunet!phcisa!frans (Francois Staes) > > > UUCP: ...!ukc!warwick!steve Internet: steve@maths.warwick.ac.uk > JANET: steve@uk.ac.warwick.maths PHONE: +44 203 524657 > > Chris Crampton. uucp: cmc@ecrc.uucp ..!unido!ecrc!cmc > ECRC GmbH Internet: cmc@ecrc.de > Arabellastrasse 17 > D-8000 Munich 81 > Germany Tel.: +49 89 92699 138 > > +-----------------+---------------------------+-----------------------------+ > | Bill Poitras | Polygen Corporation | {princeton mit-eddie | > | (bill) | Waltham, MA USA | bu sunne}!polygen!bill | > | | FAX (617)890-8694 | bill@polygen.com | > +-----------------+---------------------------+-----------------------------+ So it appears that the problem is real, but no one knows quite what it is. Mailtool is probably doing something it shouldn't, but the server should protect itself against such things.
