FreeBSD terra.ddns.tomesoft.de 5.3-RELEASE-p5 FreeBSD 5.3-RELEASE-p5 #0: Thu Jan 27 20:31:57 CET 2005     root at terra.ddns.tomesoft.de:/usr/obj/usr/src/sys/GENERIC  i386
>Description:
Building security/cryptopp with the default compile options yields to 
to a build with 'g++ -O -pipe -march=pentium -fPIC -msse2 -pipe'.
Option -O optimizes for speed and size. This produces incorrect code with some encryption algoritmns and yield to crashes.

>How-To-Repeat:
- build port
- run cryptest v
cryptes crashes with core dump after executing 
'BlumBlumShub validation suite running...' test
>Fix:
add the following patch (which supresses optimization) to the port and all tests succeed
