Summary: Compiling with optimizations causes the compiler to
fail.

Here is possible code transformation to equivalent form, where this
optimization can be simply applied. This change also has a bit surprising side
effect, second nested while loop is unrolled.

The very same bug is present in 9.0
The problem goes away if you change to pdp-11/40 rather than pdp-11/10 using
-m40 option.

I used a cross compiler, so ulong_type is easy enough to check. For
simple-object-elf.i I see
__extension__ typedef unsigned long long uint64_t;
...
__extension__ typedef uint64_t ulong_type;
which looks right.

Note typedef has a similar issue and you don't even need to have main or an use
of test to show the issue:

I thought I had a dup of this bug somewhere which was asking for this
optimization to moved to -O2 (and -Os) and above rather than keep it at -O3 and
above.

Then again, the "problem" would disappear if the middle-end could be made to
understand that memcmp(&p, &q, sizeof p) is the same thing as p == q for any
integer or pointer types p and q. So maybe it is a mid
