--- Comment #9 from Josef Melcr <jmelcr at gcc dot gnu.org> ---
The edge redirection code in the target clone pass recreates references, but it
doesn't create them with their call statements set. This causes the code in
redirect_callee to not find the ref, as it cannot match it by its call
statement, which leads to the ICE. Seems like an easy fix, currently testing
the patch below.
