Logging Extension causes crashes in Bro 2.5 Beta 6

Description

When using new Log::default_ext_func to specify source tag information (see BIT-1675 for related discussion), Bro crashes during some sort of value rendering. See Detailed backtrace for details. It always crashes for me at this line. Which ever process is logging (whether logger or manager) this happens. It crashes in as little as 5 seconds or up to about a minute of runtime.
