Re: [Boost-users] Problem with boost serialization with an existing 'struct load'

Please send me a copy of any replies to this message.

The patch below (against the RC_1_34_0 version from CVS) adds the test
program for the "struct load" bug to the serialization library's test
suite.

This program fails with post-1_31 versions of boost on all the
gcc systems I have access to, including gcc 3.2.2, gcc 4.0.2, and gcc
4.0.3.

However, the program did work with boost 1_31 on gcc 3.2.2, so from my
viewpoint it's a regression in boost.
