segv in 21.1 on Irix

From: Rohan Hart
Subject: segv in 21.1 on Irix
Date: Mon, 10 Dec 2001 14:28:54 +1300 (NZDT)

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.1.2 (mips-sgi-irix6.5, X toolkit, Xaw3d scroll bars)
 of 2001-11-13 on metro
configured using `configure  --prefix=/usr/shared-apps/ 
--bindir=/usr/shared-apps/bin/mips --libexecdir=/usr/shared-apps/libexec'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Start emacs
load inbox file: C-x C-f ~/Mail/inbox
remove last email: M-> C-r from vm C-w
save: C-x C-s
start vm: M-x vm

emacs will load vm and bbdb then crash at an unknown function...
  warning: Warning: GDB can't find the start of the function at 0xfb65c1c.
This same crash location has occured several times depending on the
contents of the file, it should currently fail with:

0x10310acc "sit-for"
0x10708c78 "vm-display-startup-message"
0x1030f928 "byte-code"
0x105cb9c4 "vm"
0x1030f9d4 "call-interactively"
0x1030af1c "execute-extended-command"
0x1030f9d4 "call-interactively"

but has also crashed at:

0x1030ca7c "read-char"
0x1030f928 "byte-code"
0x106ca1bc "vm-read-password"
0x1030f928 "byte-code"
0x108b1040 "vm-imap-make-session"
0x1030f928 "byte-code"

0x1030f928 "byte-code"
0x105cbad4 "vm"
0x1030f9d4 "call-interactively"
0x1030af1c "execute-extended-command"
0x1030f9d4 "call-interactively"


0x10316880 "scroll-up"
0x1030f928 "byte-code"
0x1030f928 "byte-code"
0x1030f928 "byte-code"

0x1095bff8 "vm-show-current-message"
0x1070acc8 "vm-preview-current-message"
0x1030f928 "byte-code"
0x105cb9f8 "vm"
0x1030f9d4 "call-interactively"
0x1030af1c "execute-extended-command"
0x1030f9d4 "call-interactively"

and when comparing the file to a successful load (seems to always
crash when running under gdb but succeeds occasionally when run by

0x10310acc "sit-for"
0x1079d7dc "ediff-setup-control-frame"
0x1079d474 "ediff-setup-windows-multiframe-compare"
0x10350380 "ediff-setup-windows-multiframe"
0x1079cf50 "ediff-setup-windows"
0x10504910 "ediff-setup"
0x103fcac0 "ediff-buffers-internal"
0x1034f924 "ediff-buffers"
0x1030f9d4 "call-interactively"

It seems that unless this is done immediately emacs has loaded then it
will load correctly.  Unfortunately it then crashes essentially at
random at some later date.

I can provide the exact file if necessary, didn't include it here as I
don't want a chunk of my inbox published to the world.

I had to install a local copy of Xpm as the default in Irix6.5 is
fractionally to old.
