--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. More likely loop-distribution related:
t.c:19:3: internal compiler error: in operator[], at vec.h:749
while (sa < 1);

Please submit a full bug report,
with preprocessed source if appropriate.
so we outline the IFN call but we obviously need to remap the loop indices.
