Comment (by catalyst):

 Oh!  After experimenting a bit more, this bug also seems dependent on the
 lack of a system `tor` binary in `$PATH` for reasons I don't yet
 understand.

 {{{
 tlyu at arcadia:~/src/tor$ PATH=/tmp/tor-stem:$PATH ../stem/run_tests.py
 --tor ./src/or/tor --all --log notice
 }}}

 successfully finds `./src/or/tor` and runs it.

 {{{
 Starting ./src/or/tor...

   May 24 15:36:09.928 [notice] Tor 0.3.1.1-alpha (git-af98b862a51c001e)
 running on Linux with Libevent 2.0.21-stable, OpenSSL 1.0.2g, Zlib 1.2.8,
 Liblzma N/A, and Libzstd N/A.
 }}}

 `/tmp/tor-stem/tor` is a shell script that just runs `kill -ABRT $$`, so
 it's clearly not producing the quoted output.  Of course, now
 `test.integ.version` fails because of the unusual execution properties of
 the "system" `tor`.
