Spoke to soon.  It passed with just MINSIGSTKSZ if run in isolation, but not with the other tests:

  make btest OPTS="--sets=thread" => works
  make btest => works
  make check OPTS="--sets=thread" => crashes
  make check => crashes

This isn't that surprising as malloc can fail anytime there isn't enough memory (even if you are only requesting 1 byte).  I think the only way to fix this is to either ignore the malloc error (risky) or safely raise a NoMethodError (safer, but I'm not sure how to do it).
