Bug ID: 48075
Summary: opt -memcpyopt crashing with Assertion `isa<X>(Val) &&
"cast<Ty>() argument of incompatible type!"' failed.
Product: libraries
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Scalar Optimizations
Assignee: unassignedb...@nondot.org
Reporter: mikael.hol...@ericsson.com

bbi-48944.ll reproducer
Reproduce with:
opt -S -o - bbi-48944.ll -memcpyopt
Result:
opt: ../include/llvm/Support/Casting.h:269: typename cast_retty<X, Y
*>::ret_type llvm::cast(Y *) [X = llvm::PointerType, Y = llvm::Type]: Assertion
`isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
This seems to be rather old, I've reproduced it with saved builds from July
2019.
