troubles with ginac 1.2 on debian unstable

[Andrius Kurtinaitis]

Hello,

i was so happy about 1.2 release, that I downloaded the new 1.2 version 
of ginac, compiled and installed on my debian unstable machine, using 
usual configure, make, su, make install. I also have another ginac 
version 1.1.6-1 installed.

When I build a simple proggy using ginac, I use new (1.2) ginac lib and 
the old cln:

g++ -o charpoly charpoly.cpp /usr/local/lib/libginac.a -lcln

The resulting program crashes with the segmentation fault. Even if it 
does nothing. Including <ginac/ginac.h> and compiling the empty program 
is enough to produce the segfault.
The current installation contains the cln version 1.1.6-1.

Any hints?

I thought, it is because of version incompatibility between the cln 
library and the new ginac. Then i tried to download the newest cln, 
which, according to its site should be 1.1.7. But the download site 
ftp://ftpthep.physik.uni-mainz.de/pub/gnu/ does not contain this version...

Or is it because of different compiler versions used to compile cln and 
my own ginac 1.2?

Any ideas?
