[Bug gas/648] New: Gas allows symbols equated to common symbols.

[hjl at lucon dot org]

Gas allows symbol equated to common symbols. But it doesn't work as
expected:

http://sources.redhat.com/ml/libc-hacker/2005-01/msg00015.html

address@hidden gas]$ cat x.s
.globl __libc_errno
        .set    __libc_errno,errno
        .comm   errno,4,4
address@hidden gas]$ ./as-new -o x.o x.s
address@hidden gas]$ nm x.o
00000004 C errno

With this patch,

http://sources.redhat.com/ml/binutils/2004-02/msg00066.html

I got

address@hidden gas]$ gcc -c x.s
x.s: Assembler messages:
x.s:3: Error: `__libc_errno' can't be equated to common symbol
