Subject: [Backport r51225 | neal.norwitz]

Try to handle a malloc failure.  I'm not entirely sure this is correct.
There might be something else we need to do to handle the exception.

Klocwork # 212-213

[I think this needs more work; a malloc() failure will cause a match to fail,
 but nothing raises MemoryError.  I'll work on this on the trunk and backport.
