Hi,

Something mightily weird is going on at your end. It doesn't fail here 
(see below). First of all, what is your configuration (output from 
`dovecot -n`)?

Also, can you make a hex dump of the binary (using `sieve-dump -h 
<your-script-binary>.svbin`). See below for an example at my end.

Finally, can you try to explicitly delete the binary (preferably after 
preserving it elsewhere) so that it is guaranteed to be created fresh? 
That should not matter, but you never know.

## Success at my end:

As said the svbin is identical to the one create by the previous version.

Comparing the dump:
Block 0 differs because it has the source file name.
Block 1 is identical
Block 2 is identical. It is this block that is declared corrupt.

The line numbers differs and 86400 is read as 5.  It is like it has 
forgotten the size of an integer or is confused about endianness.  There 
is something strange, like an #if that guesses wrong.  At least I have 
somewhere to start looking.

Thank you for checking at your end, I was worried the RC had introduced 
an error and your result suggests not.  RCs are for testing and I am.

This is correct.  I believe there to be a compiler problem.  Removing 
optimisation from sieve-binary-code.c gives success.

Thank you to Stephan Bosch for testing this for me and pointing me in 
the right direction.

My debugging was confused because dovecot flags are passed to 
pigeonhole, eg $DOVECOT_CFLAGS.  This is why the build of dovecot 
affects pigeonhole.  Once I removed these I could control the pigeonhole 
build and I was able to isolate the problem.
