test case, containing a non-ASCII byte

Hi,

compiling an .ascii "\x" statement where x is a special byte such as 0xC3 (that
is a valid character in some text encodings) triggers an assertion failure in
gas 2.25. I've attached the test case 1.asm.

$ file 1.asm 
1.asm: ISO-8859 text

Compiling with gas 2.25 i686-linux-gnu (from Ubuntu) and i686-w64-mingw32 (from
MinGW-w64):

1.asm: Assembler messages:
1.asm:1: Internal error!
Assertion failure in stringer at ../../gas/read.c line 5323.
Please report this bug.

For comparison, with the previous version, gas 2.24 i686-w64-mingw32 (from
MinGW-w64):

1.asm: Assembler messages:
1.asm:1: Warning: unterminated string; newline inserted
1.asm:2: Error: junk at end of line, first unrecognized character valued
0xffffffbc
