Patch created on April 03 2014
Patch Case#: 188703
//****************************************************************

Problem :
Due to a problem in the Quartus II Software version 13.0 and later, a
fatal error may be seen when launching Quartus II on Linux machines
running RedHat / CentOS 6.<X> distributions installed with newer and
older versions of the libcrypto.so library (libcrypto.so.1.0.1e and
libcrypto.so.0.9.8e.) which is installed by the openssl and some other
packages.

The Error message seen may be similar to the following:

*** Fatal Error: Segment Violation at (nil)
Module: quartus
Stack Trace:

    0x80106: lh_insert + 0xa6 (crypto.so.6)
    0x5c8eb: OBJ_NAME_add + 0x6b (crypto.so.6)
    0x4f571: SSL_library_init + 0x1d1 (ssl)

Solution :
This patch disables the code that triggers the segfault. 

Caution - You must either have previously installed the
          Quartus II 13.1 software or must
          install the Quartus II 13.1 software
          before installing this patch. Otherwise, the patch will
          not be installed correctly and the Quartus II
          software will not run properly.
