Description of problem:
Racoon daemon built on a 64-bit platform segfaults when setting the security
context into a proposal from a 32 bit platform. 

Version-Release number of selected component (if applicable):
ipsec-tools-0.6.5-6

How reproducible:
Happens all the time when negotiating between a 64-bit and 32-bit built app.

Steps to Reproduce:
1.setup ipsec policy between a ppc (with 32 bit apps) and a x86_64 (with 64-bit
apps)
2. start racoon on both machines
3. do a ping from a 64-bit to 32-bit or vice versa
