Build: [7 regression] ICE in build_noexcept_spec, at
cp/except.c:1196
Between 20161107 (r241917) and 20111108 (r241972), many C++ testcases started
to FAIL with
an ICE:
+FAIL: g++.dg/concepts/expression.C (internal compiler error)
+FAIL: g++.dg/concepts/expression.C (test for excess errors)
+WARNING: g++.dg/concepts/expression.C compilation failed to produce
executabl
