Indeed. Same symptoms at least:
(gdb) call debug_generic_expr (chrec)
{0, +, {2, +, 1}_4}_4
This one fails for me with -m32 only though.
The chrec isn't quite {2, +, 1}_4 - I think the IV evolves as 0, 3, 4, 5, 6

Fails on x86-64-linux with
gfortran -m32 -O1 -ftree-loop-linear
but works with -m64.

This is most likely related to PR 40281.
