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,
...
if I parse it correctly. That looks more like a loop like
for (i=0;; ++i)
for (j=i+3;; ++j)
...
where we somehow cleverly analyze this as a single loop... (?).
Sebastian - please have a look here and/or at PR40281.
