Hi,

I fixed the above problem (I was still pulling in the 3.4 build of
boost).  Now I'm correctly pulling in only stuff built with gcc32
(ldd confirmed this).

But the program still segfaults.  Here's an excerpt from the gdb
back trace after a crash.  Basically, everything prior to #32 is our
own code, and #32 is where the boost serialization code is first
referenced.  (I can certainly post the whole backtrace, just trying
to be concise.)  Note "MyClass" is the name of our custom class that
uses boost::serialization:
