[crash]

[ Cross posted to debian-devel: Please advise. I don't know a lot about this stuff yet. ] I was editting a Debian bug report (against perl-5.005-base; POSIX.pm is broken) with EDITOR set to `xg', my script that runs XEmacs if there's no gnuserv, or gnuclient if there is a gnuserv... I clicked the [Done] button, clicked [Yes] on the dialog box, and XEmacs crashed, with the following to say... (luckily, I just happened to be running it under gdb inside a screen.) Also attached is the Installation file. It linked against Xaw3d/libXaw, even though I told it `athena', not `athena3d'... Hmmm. I wonder if I have the flat athena -dev kit installed even? I'd better check before I send this... It's there. Looks like it's part of the base X11 -dev installation... Hmmm. What's wierd, is that in the filesystem, the symlink from /usr/X11R6/lib/Xaw.so.6 points to Xaw.so.6.1, which is sitting right next to it. In the subdirectory Xaw3d, "libXaw.so.6" (NOT "libXaw3d.so.6") is a symlink back out a level to the libXaw3d.so.6.1 library. All through the (attached) config.log, things are linked with `-lXaw'. When XEmacs starts, it says: /usr/local/src/XEmacs/xemacs-21.2/src/xemacs: Symbol `toggleClassRec' has different size in shared object, consider re-linking /usr/local/src/XEmacs/xemacs-21.2/src/xemacs: Symbol `labelClassRec' has different size in shared object, consider re-linking I will try running with a LD_PRELOAD and see what happens... Hey, in /etc/ld.so.conf, the Xaw3d lib is listed FIRST, at the top of the file. I bet that's what's wrong. Do yous think so? Should I report this as a bug against the Debian Xaw3d package? I think that's the correct course of action here. I'm starting to think I ought not send this after all... Ok, I've verified that if I use a LD_PRELOAD pointing to the flat libXaw.so.6.1, the "Symbol" errors don't print on startup. (And with the same LD_PRELOAD, ldd of course shows the flat libXaw) That is likely what caused this and several other crashes. I can see that it's not the fault of the XEmacs developers, but an error in the system configuration. I will edit /etc/ld.so.conf, and investigate the libXaw3d-dev package. % ldd /usr/local/src/XEmacs/xemacs-21.2/src/xemacs libXaw.so.6 => /usr/X11R6/lib/Xaw3d/libXaw.so.6 (0x4001c000) libtiff.so.3 => /usr/lib/libtiff.so.3 (0x4006f000) libpng.so.2 => /usr/lib/libpng.so.2 (0x400b2000) libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x400d9000) libz.so.1 => /usr/lib/libz.so.1 (0x400f9000) libcompface.so.1 => /usr/lib/libcompface.so.1 (0x40108000) libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0x40114000) libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x40122000) libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x40134000) libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x4017c000) libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40188000) libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40227000) libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40231000) libdl.so.2 => /lib/libdl.so.2 (0x40247000) libdb.so.3 => /lib/libdb.so.3 (0x4024b000) libgpm.so.1 => /usr/lib/libgpm.so.1 (0x40286000) libncurses.so.4 => /lib/libncurses.so.4 (0x4028c000) libesd.so.0 => /usr/lib/libesd.so.0 (0x402cb000) libaudiofile.so.0 => /usr/lib/libaudiofile.so.0 (0x402d3000) libm.so.6 => /lib/libm.so.6 (0x402e6000) libopenldap.so.1 => /usr/lib/libopenldap.so.1 (0x40303000) liblber-openldap.so.1 => /usr/lib/liblber-openldap.so.1 (0x40318000) libc.so.6 => /lib/libc.so.6 (0x4031d000) /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
