Hi,
I've seen a new variant of this crash, where the same assertion is triggered:
opt -slsr -S -o - bbi-54843.ll
Result
opt: ../lib/Analysis/ScalarEvolution.cpp:5681: llvm::ConstantRange
llvm::ScalarEvolution::getRangeForUnknownRecurrence(const llvm::SCEVUnknown *):
Assertion `L && L->getHeader() == P->getParent()' failed.
Also in the new reproducer there is dead code present, but this time the dead
block is mentioned in a PHI in a reachable block.
