More information: it crashes when it tries to do the dereference in the
above statement.  I think it may be an alignment problem; the location
pointed to by (buf+OFFSET_MODSEQ_64) is not aligned on an 8-byte
boundary, and I am able to dereference the location 4 bytes before or
after that location.

I don't know the best way to fix this, but I suspect memcpy() will do
the right thing (on big-endian machines).
