Related to the attempt to upgrade Racket to 6.12:
  https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30603

Apparently the patch I proposed may break GC, so another option should
be found.  But more interestingly is that my thought that things broke
because of a change from Racket 6.11 to 6.12 appears to be wrong... I am
also getting a similar error in trying to build Racket 6.11.  I assume
this must be a dependency change but I don't yet know which:

It seems that Racket last built successfully in late December:
