v2.3.3 rc1 - Error: sieve: !!BUG!!: Binary compiled from dovecot.sieve is still corrupt

[James]

I have a sieve problem with dovecot v2.3.3 rc1 with either of pigeonhole 
0.5.2 or 0.5.3.rc1.  The the change that triggers this is in dovecot not 
pigeonhole.  Sieve filtering has been working with v2.3.2 and many 
earlier versions.

This is a sieve script with a vacation handler.  My other sieve filters 
are working.  My actual sieve filter worked before and was written by 
Roundcube web mail.  My failing test script is cut-n-paste from the 
sieve examples https://wiki2.dovecot.org/Pigeonhole/Sieve/Examples so 
should not be in doubt.

The text script compiles to dovecot.svbin and newly compiled files are 
identical to older versions, the compilation has not changed.
