linking a code with

[Zvi Vered <veredz72@xxxxxxxxx>]

Hello,

I built the code in guided_tour.dox with libssl.so, libcrypto.so I created
(with last version of openssl):

gcc Main.o -o Main.out /home/my_user/GNU/libssh-0.6.3/build/lib/libssh.so
/home/my_user/GNU/openssl/lib/libssl.so
/home/my_user/GNU/openssl/lib/libcrypto.so

and got the following message:

/usr/bin/ld: warning: libssl.so.6, needed by
/home/zvivered/GNU/libssh-0.6.3/build/lib/libssh.so, may conflict with
libssl.so.1.0.0
/usr/bin/ld: warning: libcrypto.so.6, needed by
/home/zvivered/GNU/libssh-0.6.3/build/lib/libssh.so, may conflict with
libcrypto.so.1.0.0

When I ran Main.out I got the following crash:

*** glibc detected *** ./Main.out: malloc(): memory corruption: 0x09d0fae0
