In Isabelle2016, I get the following weird sledgehammer output.
Sometimes, (I could not reproduce with small example), I also get the
message that e derived false from these facts, and that I should report
this as a "bug" in sledgehammer.
using ASSERT_simps(1) inres_simps(3) pw_ASSERT(2)
sledgehammer [provers = e]
"e": Try this: by metis (> 1.0 s, timed out).
