Dovecot crashing when attempting to search in virtual folder with fts_squat activated

Hi everyone,

I am running into a problem when trying to use fts_squat in a virtual 
folder. Without fts_squat plugin the search (from, subject...) works in 
all folders. With activated fts the search on the inbox folders works 
expectedly well but any attempt to search anything in any virtual folder 
leads to the following error. Similarly when attempting "doveadm fts 
lookup". I also noticed that no search index for the virtual folders 
gets build - is this expected behaviour?

Dovecot crashing when attempting to search in virtual folder with fts_squat activated

Hi everyone,

I have now updated to dovecot 2.3.4.1 - unfortunately the issue still 
persists. Can anyone help me figure out if this is due to a 
misconfiguration on my part or another error?

Any help is greatly appreciated!

Cheers
Benjamin

Dovecot crashing when attempting to search in virtual folder with fts_squat activated

fts_squat was deprecated in 2.1.  There's a high likelihood it is buggy in a
variety of ways in any recent Dovecot release.
