Comment (by olly):

 Interesting - `*hint` shouldn't be NULL at this point, as we check for
 that on the line before; `hint` shouldn't be NULL either, as it's just a
 pointer to a member of the object we call this from (and the stack shows
 it isn't).

 My guess is that the postlist pointed to by `*hint` ends up deleted at
 this point, though I've not yet managed to reproduce that.

 Can you print the variables involved, in gdb:

 p hint
 p *hint
 p (*hint)->get_description()->c_str()
 p term->c_str()
 p *this
