Package: treetool
Version: 2.0.2-1
When trying to open a treefile treetool crashes with Floating Point
Exception. I have tried to open treefiles generated by Paup (in phylip
format) as well as Phylip. Perhaps it is in this case useful to mention
that my computer is an Alpha LX164 with a 21164a CPU.
During startup of treetool XView emits warnings of this kind:
XView warning: Notifier error: Unknown client
XView warning: win_send: Unknown client
The last messages of strace -f -v look like this:
brk(0x120282000) = 0x120282000
brk(0x120284000) = 0x120284000
brk(0x120286000) = 0x120286000
brk(0x120288000) = 0x120288000
read(7, "", 8192) = 0
read(7, "", 8192) = 0
read(7, "", 8192) = 0
--- SIGFPE (Floating point exception) ---
+++ killed by SIGFPE +++
My computer still has a 2.2.14 kernel installed.
Versions of installed packages are:
libc6.1 2.1.3-10
xlib6g 3.3.6-7
xviewg and xview-clients 3.2p1.4-9
Regards,
Kerstin

Distribution: unstable
Urgency: low

Description:
treetool - [Biology] An interactive tool for displaying trees
Closes: 66190
Changes:
treetool (2.0.2a-2) unstable; urgency=low
.
* Really changed the Maintainer address in control field
* Some additions to README.Debian
* added new source location to copyright file because the original
was unavailable
* Compile on alpha with -mieee to avoid arithmetic exceptions
Many thanks to Helge Kreutzmann <kreutzm@itp.uni-hannover.de>.
closes: #66190
General remark: The fix from Helge just fixes a symptom, not the reason
of the problem. The system is that there is a "Divide by zero" error
which is now handled as suggested by IEEE which is not the default on
Alpha architecture.
On the other hand the value which becomes zero should definitely not be
zero. The problem could be verified using the patch
debug.debian.patch.alpha (for the Debian-Version of treetool/size.c) or
debug.debian.orig.alpha for the original treetool/size.c). This simple
patch uses two printf statements to show the problem for further debugging.
The value of nd->x just becomes 0 even if it is not touched. The reason
may be some strange handling of pointers and doubly linked lists.
The code produces lot of warnings and should definitely use a more
robust implementation of doubly linked lists (for instance from glib).
The problem is that this program has simply no license thus further
development is quite hard.
