The patch LGTM. And I agree that the fix is not needed for 3.4. Thanks, Serhiy.
I verified that it does solve the "embedded" problem (case 1 above) when using
embedded versions of all previous releases of 2.7.x (except 2.7.0) and 3.3.x.
For the record, it appears 2.7.1 introduced a separate incompatibility issue
that causes a similar initialization crash with an embedded version of 2.7.0:
Traceback (most recent call last):

Googling shows a number of reports of users who have run into that one, too,
though no one seems to have opened an issue here about it. I don't think it's
worth trying to fix that one at this point as there probably aren't that many
instances of system executables that still have embedded static 2.7.0
interpreters anymore (I hope). Unfortunately, that's not the case for embedded
static 2.7.2, e.g. vim on OS X 10.8.x.
