Maybe that explains also a regression visible only on i686 (32-bit host).
It still PASSes on x86_64 (64-bit host) with either native od 32-bit inferior
(-m32):

The length is bogus (it is %rax or %eax) but it should be some number.

i686:
ptype reg_string^M
type = char [variable length]^M
             ^^^^^^^^^^^^^^^
(gdb) FAIL: gdb.dwarf2/dw2-bound-loclist.exp: ptype reg_string
p reg_string^M
Insufficient memory in host GDB for object of size 4160138653 bytes, maximum allowed 536870911 bytes.^M

x86_64 or x86_64 -m32:
ptype reg_string^M
type = char [4160048541]^M
(gdb) PASS: gdb.dwarf2/dw2-bound-loclist.exp: ptype reg_string

Attaching the Fedora testcase.
