I still think that handling NULL from evolution_part_in_loop_num is the
correct thing to do. Even if you need to move this check to the analysis
phase.
The interesting thing is that the

For access function (short int) {(short unsigned int) i_44, +, 1}_1)
evolution_part_in_loop_num() returns NULL, which causes the failure.
I tried to peel NOP_EXPRs from POLYNOMIAL_CHRECs in

Can't you simply handle a NULL return
from evolution_part_in_loop_num in the vectorizer?
The problem is that this happens during the transformation (for the code
created by the vectorizer).
