When, I come to think of it, I had the same problem (crash at saving
time) a few weeks ago on Mandrake cooker. It disappeared when updating
to a later cooker version.  I don't know what was the difference.

gcc 3.2 is fairly new, so the jury is still
out to determine what is the cause of some other problems.
My bet is that some bugs just uncover other latent ones.

The problem when Joris allocation stuff is in is still there.
I wish we had a C++ guru on board.

Thx for your feedback, Felix.

PS: if it can help, here what says gcc about its configuration.

gcc -v Reading specs from
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.2/specs Configured with:
../configure --prefix=/usr --libdir=/usr/lib --with-slibdir=/lib
--mandir=/usr/share/man --infodir=/usr/share/info --enable-shared
--enable-threads=posix --disable-checking --enable-long-long
--enable-__cxa_atexit --enable-languages=c,c++,ada,f77,objc,java
--host=i586-mandrake-linux-gnu --with-system-zlib Thread model: posix
gcc version 3.2 (Mandrake Linux 9.0 3.2-2mdk)
