Bro core dump in logical operations with vector and scalar types

This code crashes Bro with a core dump :

event bro_init() {
local v : vector of bool = { T, F, T };
print v && T; # OK, print [T, F, T]
print v || F; # OK, print [T, F, T]
print v && F; # KO, print [F, F, F]

1. then : internal error: bad reference count [2], then core dumped
   print v || T; # KO, print [T, T, T]

2. then : internal error: bad reference count [2], then core dumped
   }
