The crashing IR.
The attached IR fails with:
lib/Transforms/Scalar/Reassociate.cpp:1532: llvm::Value *<anonymous
namespace>::Reassociate::OptimizeAdd(llvm::Instruction *,
SmallVectorImpl<<anonymous>::ValueEntry> &): Assertion `NumAddedValues > 1 &&
"Each occurrence should contribute a value"' failed.
I've tried to create a minimal IR test case, that you can just run with:
opt -reassociate reassoc-crash.ll</pre>
