--- Comment #12 from Richard Biener <rguenth at gcc dot gnu.org> ---
So here I think the issue is that there's a mismatch between alias and
clobber/use constraint building where the former handles __builtin_strdup, not
making its argument escape, but the latter does not, assuming it's good enough
to use what escapes:
c_4 = &HEAP(35)
doubledereftmp(36) = *xstrdup.arg0 + UNKNOWN
*c_4 + UNKNOWN = doubledereftmp(36)
xstrdup.clobber = ESCAPED
xstrdup.use = ESCAPED
