DB 3.0.55, memset() and overoptimizacion [#1395]

[Sleepycat Software]

Hi, my name is Keith Bostic and I'm with Sleepycat Software.  Amy Adams
asked me to review your Support-Request.

After talking to some folks, my understanding is that this is a bug in
our code.  The compiler, according to ANSI C, is permitted to assume that
a structure is properly aligned (not just that its elements are properly
aligned, but that the structure itself is aligned).  We'll be fixing this
in our source tree.  If you want a general fix, I can send you one,
although the workaround you used is probably just fine.

Regards,
