In "git show RELEASE-4.5.1:tools/libxl/xl_cmdimpl.c" line 7102 is a blank
line. The next line is:
     config = xlu_cfg_init(stderr, config_src);
which might be the culprit but also might not be.

Are you running pristine 4.5.1 or are the (perhaps gentoo added) patches?
Can you figure out what line 7102 of that might be.

It's not clear yet, since it might be a backport of a buggy patch, but it's
starting to look a bit that way. Once xl_cmdimpl.c:7102 and the list of
patches is clarified I think we'll know one way or another.
