Hello, again
I sent a report on Feb 4 about this bug, but at that time there was no
debug information available. My environment is the following:
Pentium 133, Slackware Linux 3.4 (heavy modified)
Kernel version 2.0.33
GCC version 2.7.2.3
Xforms version 0.88
Running `ldd lyx' I get
libforms.so.0.88 => /usr/X11R6/lib/libforms.so.0.88 (0x4000a000)
libXpm.so.4 => /usr/X11R6/lib/libXpm.so.4 (0x4008a000)
libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40098000)
libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x400a0000)
libc.so.5 => /lib/libc.so.5 (0x400b4000)
libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40170000)
libg++.so.27 => /usr/lib/libg++.so.27 (0x4020c000)
libstdc++.so.27 => /usr/lib/libstdc++.so.27 (0x40244000)
libm.so.5 => /lib/libm.so.5 (0x40276000)
I used the options `--prefix=/usr --with-included-gettext' to configure.
After opening and closing an existing note I tried to remove it moving the
cursor to it's left side and pressing Delete but LyX broke with a core
dump. An emergency copy was saved [Try this with M$ W@®Ð, ha,ha,ha! Even
a LyX *bug* is better than Bill's word processor, great job guys! ].
This time gdb gave the following information:
$ gdb lyx -c core

I was unable to reproduce the bug by simply opening, closing and deleting
a note again. Could this to be a bug in XForms, as JMarc pointed out
before?
I found that `gsignal' is a function in libc.so.5.4.44 (declared in
/usr/include/signal.h) but what's the strange `??' calling it?
