One of the things that I have noticed is that the 2.2.8 config.h is
showing HAVE_MMAP is enabled. Unless something else is done, this
bypasses the stm_read module which handles the conversion from VFC to
stream. This could be the cause of the corruption, but until I get to
the point of doing some testing, I do not know for sure.
If you can rebuild Samba with out the HAVE_MMAP defined, it may fix the
issue.
If you reference the source OpenVMS Porting Library used with Mozilla,
they have a wrapper on the MMAP code so that they simulate it for
non-stream or binary files.

Currently it is probably the most useful method for me to track the
issues that are important.
I have entered bug report as BUG 1816.
I probably will not be able to address this issue for a while, and I
will be converting to use a VFS module first, as it simplifies the debug
path.
