Oh wow, a bug in gcc!!
Objects/unicodeobject.c: In function ‘unicode_isupper_impl’: Objects/unicodeobject.c:15661:1: internal compiler error: in create_edge, at cgraph.c:850 } ^ Please submit a full bug report, with preprocessed source if appropriate. See file:///usr/share/doc/gcc-6/README.Bugs for instructions.
I wonder if this is because the builder was updating gcc in the middle of this operation, as this looks very suspiciously related to:
https://buildbot.python.org/all/#/builders/128/builds/915
New builds are OK.
