Hello!
I use 0.9.8-stable-SNAP-20050601 snapshot. Problem occurs on digest
signing.

Native tests are passed. So I do:

keyrsa.pem -out reqrsa.pem -config apps/openssl.cnf
LD_LIBRARY_PATH=. ./apps/openssl x509 -req -set_serial 1 -signkey keyrsa.pem
-in reqrsa.pem -out certrsa.pem
LD_LIBRARY_PATH=. ./apps/openssl dgst -sha1 -sign keyrsa.pem -out dsignrsa.bin

It causes a segfault with backtrace

When I specify -rand, segfault doesn't occur
LD_LIBRARY_PATH=. ./apps/openssl dgst -sha1 -sign keyrsa.pem -out dsignrsa.bin
-rand /dev/random CHANGES
finish successfully.
The same problem is on smime.
I do:
======
LD_LIBRARY_PATH=. ./apps/openssl smime -encrypt -binary -in CHANGES -aes256
-out encryptionrsa.pem -outform pem certrsa.pem
LD_LIBRARY_PATH=. ./apps/openssl smime -decrypt -binary -in encryptionrsa.pem
-recip certrsa.pem -inkey keyrsa.pem -out smime_decrrsa.dump -inform pem

Segfault occurs on decrypt with the same backtrace:

=========
The problem doesn't exist on 20050523 snapshot.
Thank you.
PS. We have a extra test suite testing openssl executable.
Unfortunately, it's GNU make specific. Are you interested in it?
