Comment (by gk):

 UBsan is actually involved/responsible for the freeze while compiling the
 startup cache. This got "solved" by https://hg.mozilla.org/mozilla-
 central/rev/f78c80504443 which is probably by accident as an exception is
 now thrown during that step which might break the freeze:

 Might be interesting to dinf out what revision was the first that caused
 the freeze given that ESR 24 is working fine...
