The testcase doesn't clean its IPA dump. However, there is also no
scan dump function, so it is questionable, what the testcase tries to
do with the dump. Also, the flags that trigger the bug in the PR are
different: "-fdevirtualize -fipa-cp -fipa-icf-functions".
Can you please check the testcase?
Uros.
