--- Comment #1 from Amara Emerson <[email protected]> ---
Should be fixed in r362666. We were trying to look through copies but then
called getVRegDef() on a physreg operand. This would normally be benign as it
returns nullptr if so, but with assertions enabled it if there are multiple
defs of the physreg (in this case due to a call instruction that imp-defs w0)
it will crash.
