Bug 122542

Let's suppose the executable of the program is located at
/usr/X11R6/bin/chemtool, then please provide the output of `ldd
/usr/X11R6/bin/chemtool'.

A backtrace (made with gdb or ltrace/strace) would also be helpful. 
For further information, please read: http://bugs.opensuse.org 

Chemtool is located in /usr/bin/chemtool    
ldd output follows:    
ldd /usr/bin/chemtool

        /lib/ld-linux.so.2 (0x40000000)    
    
If you start chemtool from console you get this message:   
  
enrico@dhcppc0:~> chemtool   
sh: babel: command not found   
Consider installing Babel/OpenBabel for file format conversions...   
Segmentation fault   
   
   
    

Every library was found, so this is not a library-problem.
Please attach (!) the output of `ltrace /usr/bin/chemtool'.

It say's `consider' here which indicates that this external command is not
required to run this problem. Let's see where it crashes exactly.

ltrace  /usr/bin/chemtool

Ok, I can reproduce it, thanks for the report. I'll try to fix it soon. 

It's caused by a bug in gcc-4.0, which makes things little bit
complicated. A workaround is

a) compile with an older gcc

b) don't compile with -O2

c) apply this patch to the source (note that there isn't any bug in
chemtool, this just avoids the gcc bug):

Thank you!
I changed the summary of this bug to a more generic form.
Can Novel provide an rpm compiled with the patch above?

> Can Novel provide an rpm compiled with the patch above?

I don't know whether or not there will be an update for SUSE Linux 10.0,
but you can try the patched package from OpenSUSE:

http://ftp.opensuse.org/pub/opensuse/distribution/SL-OSS-edge/inst-source/suse/i586/chemtool-1.6.7-2.i586.rpm

Let's not do the update for 10.0.  I've opened a bugreport for the GCC issue.

Actually, there was a bug in chemtool (part of stack overwritten), it
just didn't show up until gcc-4.0 on i386. Many thanks to Richard
Guenther for finding the bug. The fixed package should appear in
OpenSUSE edge soon.
