 I can intermittently reproduce this with Python 2.7. Some of the time,
 the build succeeds, other times it hits the Python traceback previously
 reported (the output I get there is identical), other times it will seg
 fault, as below. (The example below is on Linux, so it's a cross-
 platform issue.)
 
 By "intermittently", e.g., in four test runs I just did, it hit the
 traceback once, and succeeded in the rest. I've added more debugging
 output, but am out of time tonight.
