It's a heisenbug.  It isn't the random seed itself that makes a difference, 
just the fact that things are done differently now.  Using different 
optimization flags makes a difference too.  I enabled ubsan and it detected 
badness slightly earlier than the segfault, but not early enough that I have 
any idea what might have gone wrong or when.

Out of curiosity, how many processes are you using for make test-baseline?
