Ah, I see what happens, I get the same nonsensical output as Martin when I
compile for 64-bit, but when I compile for 32-bit, I get the normal-looking
output I got before:

$ g++ -m64 -c -S -Wall 77572.cc
77572.cc:1:19: error: invalid conversion from 'const char*' to 'int'
[-fpermissive]
 constexpr int i = "\x0_\x01_\x7f_\x80_\xff";
   ^
77572.cc:1:19: error: '(int)((const
char*)"\000_\001_\177_\3777600_\377")' is not a constant expression
$ g++ -m32 -c -S -Wall 77572.cc
77572.cc:1:19: error: invalid conversion from 'const char*' to 'int'
[-fpermissive]
 constexpr int i = "\x0_\x01_\x7f_\x80_\xff";
   ^
77572.cc:1:19: error: conversion from pointer type 'const char (*)[10]' to
arithmetic type 'int' in a constant expression

I still get the same output as Martin using recent trunk, and any older
versions.

The output I get doesn't have the nonsensical escape sequences:

$ /usr/local/bin/g++ -c -S -Wall 77572.cc
77572.cc:1:19: error: invalid conversion from ‘const char*’ to ‘int’
[-fpermissive]
 constexpr int i = "\x0_\x01_\x7f_\x80_\xff";
   ^
77572.cc:1:19: error: conversion from pointer type ‘const char (*)[10]’ to
arithmetic type ‘int’ in a constant expression
$

So, FIXED? (You're usually better than me at narrowing down the revision when
the fix happened so I'll leave that to you)
