 3.0.3 do not have this bug, but I don't sure if it means that 3.1 is free
 from it -- initialy it was in 3.1 20010226

 I found file using binary search -- don't shure how to continue to the
 level of function and I don't have current gcc anyway, sorry.

I bootstraped gcc:
../gcc/configure --prefix=/usr/local/gcc --with-cpu=ultrasparc --enable-languages=c++,objc,f77 &&\
make CFLAGS='-O2' LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2 -fno-implicit-templates' bootstrap && \
make install

I build openssl-0.9.6 ( http://www.openssl.org/source/openssl-0.9.6.tar.gz )
Configure --openssldir=/tmp/ssl solaris-sparcv9-gcc && make
and run tests (make test) many of them are OK, but one is 
failed with core dump:
cd test
../apps/openssl verify -CApath ../certs ../certs/*.pem

Backtrace is:
(gdb) where
#0  0xf7d74 in BN_mod_exp2_mont ()
#1  0x992ac in dsa_do_verify ()
#2  0x98bc0 in DSA_verify ()
#3  0xa9ba4 in EVP_VerifyFinal ()
#4  0xfc310 in ASN1_verify ()
#5  0xcaffc in internal_verify ()
#6  0xcab40 in X509_verify_cert ()
#7  0x31f38 in check ()
#8  0x31af0 in verify_main ()
#9  0x312d4 in do_cmd ()
#10 0x31054 in main ()

I changed in Makefile.ssl
CFLAG= -fPIC -DTHREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -mcpu=ultrasparc -O3 -fomit-frame-pointer -Wall -DB_ENDIAN -DBN_DIV2W -DULTRASPARC -DMD5_ASM
-O3 to -O2
and try
make clean && make && make test
now all tests are OK
