This is a bug in loop.c ... which is why it works in 4.2.0 and above.

Looking into it, a bit more. But as far as I can tell this is a latent bug in
the x86 back-end.

So the problem is that loop.c creates a tree for:
(plus:SI (reg:SI 3 bx)
(const:SI (unspec:SI [
(symbol_ref:SI ("dwarf_reg_size_table") [flags 0x2] )
] 1)))
From:

Yep, and the aforementioned patch is indeed the culprit.
