I've spent the last week trying to rebuild Dovecot on my Raspberry Pi 3
(aarch64; running Slackware ARM -current) and am running into the following
build error. I suspected it may be my recent update to Slackware but I've been
able to build the same source tarball on an x86 system running
slack
Just to be complete here is a second backtrace with a similar error (if it
needs to be fixed at multiple places):
```
Panic: file index-search-result.c: line 174
(index_search_result_update_appends): assertion failed:
(result->search_args->args == &search_arg)
Error: Raw backtrace: /usr/lib/dov

I have to following panic with fts flatcurve enabled:
```
Panic: file index-search-result.c: line 132 (index_search_result_update_flags):
assertion failed: (result->search_args->args == &search_arg)
