Comment:

 ubsan says:

 {{{
 queryparser/termgenerator_internal.cc:837:26: runtime error: member access
 within null pointer of type 'const Xapian::Enquire::Internal'
 }}}

 So looks like the `MSet` ends up with a `NULL` Enquire object internal in
 this situation.  Should be an easy fix.

 Did you test 1.4.x?
