 Running {{{test.exe bridges/clear_bridge_list}}} causes this assertion:

 {{{
   bridges/clear_bridge_list: May 23 17:12:53.714 [err]
 tor_assertion_failed_():
   Bug: container.h:70: smartlist_get: Assertion sl->num_used > idx failed;

 }}}

 AFAICS, since {{{sweep_bridge_list()}}} caused all entries in
 {{{bridgelist}}} to get deleted, an index of zero is illegal. Don't ask me
 why.

 And since I compiled all {{{test/*.c}}} sources with
 {{{-DDEBUG_SMARTLIST}}}, this will trigger this abort(). I fail to see why
 this isn't done in the officially.
 \\

 PS1. I'm on Win-10, tor.exe + libs was built with MSVC 2017.
 \\
 PS2. Build tor.exe from master at 23 May 2018.
