--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
Note the immediate use verification error is
/* Avoid infinite loops. 50,000,000 uses probably indicates a
problem. */
if (count++ > 50000000)
goto error;
which is spurious, the issue is SLSR creating a gigantic function from nothing.
