Thanks a lot for taking a look, Stefan.

I have tried again with SQLite 3.7.12, but the result is the same. You
did use VC2010 for compilation, and tried with a release build, right?
Which SQLite version did you use actually?

I'm not running the test suite in parallel, and I'm also seeing it
when I run only that single test:

    python win-tests.py -c --release -t mergeinfo-test.exe#12 R:\test

Besides I'm using Python 2.7.3, which IIUC is the latest production
release of the 2.x family.
Thanks for the suggestion though.

I guess the next step for me is to try and reproduce this when running
from within the IDE ... or try bisecting.

Hm, I haven't seen that one yet (I'm looking specifically at
merginfo-test.exe, not merge_tests.py, but I did run the rest of the
test suite successfully, so this has definitely passed for me --
though as I said, I don't run them in parallel).
