Unfortunately this didnt help. But I succeeded in another way meanwhile:

The crashing tor executables were built with gcc. The one who works right now, is from Your dev tarball, but built with Suns cc plus an interesting CFLAG. I found some info in the net (http://developers.sun.com/solaris/articles/manage_core_dump.html):

The Sun Studio C/C++ compiler has the -xmemalign option, which can be used to adjust the behavior of the UltraSPARC CPU when there are unaligned memory addresses that can be determined at compile time. The -xmemalign option causes the compiler to generate additional load/store instructions for unaligned memory access. However, the -xmemalign option cannot handle unaligned memory access during runtime. If unaligned memory access happens during runtime, the developer needs to change the source code.

So I did:
make distclean
export CC=cc
export CFLAGS='-xmemalign'
./configure --enable-threads --prefix=/usr --sysconfdir=/etc --with-ssl-dir=/usr/local/ssl
/usr/local/bin/make -j 2

here I got some very unusual output:

        DEPDIR=.deps depmode=none /bin/bash ../../depcomp \
        cc -DHAVE_CONFIG_H -I. -I../..  -DSHARE_DATADIR="\"/usr/share\"" -DLOCALSTATEDIR="\"/usr/var\"" -DBINDIR="\"/usr/bin\"" -I../../src/common  -I/usr/local/ssl/include   -xmemalign -g -O -c directory.c

Might this be the reason why a gcc built crashes on Solaris? The executable was created and runs now without crashing:-)
