Hi, the following patch is a quick fix for PR 66301. eliminate_dom_walker::before_dom_children in tree-ssa-pre.c calls dump_possible_polymorphic_call_targets when dump_enabled_p returns true, but the function assumes dump_file is not NULL while the predicate also returns true when alt_dump_file is not NULL (and dump_file is).
There were no comments from the author of the new dumping interface in bugzilla and so I suggest we simply check the dump_file like almost everywhere else. Bootstrapped and tested on x86_64-linux. I do not have a testcase because the one in bugzilla is biggish and it did not seem worth reducing. OK for trunk and the 5 branch?
