Package: gcc-4.1
Version: 4.1.0-0

I get the following build failure on mips with GCC 4.1 (but not with
GCC 4.0, or with 4.1 on i386):

> Automatic build of nn_6.7.2-1 on bigsur by sbuild/mips 1.89
...
> cc -Iconf -O2 -fno-strength-reduce -fomit-frame-pointer -pipe -O2   -c -o hash.o hash.c
> hash.c: In function 'hashfetch':
> hash.c:133: error: address of register variable 'hdbmdata' requested
> make[2]: *** [hash.o] Error 1

Ben Hutchings suggests that this is a compiler bug:

17:47 <Womble2> Right, I'd say it's a gcc bug
17:48 <Womble2> It's trying to pass the address of hdbmdata as a
  hidden argument to hdbmfetch
17:48 <Womble2> which doesn't work because it's been allocated to a
  register
17:48 <Womble2> However, since that's an implementation detail, the
  use of 'register' is perfectly valid
17:49 <Womble2> gcc ought to ignore the 'register' in that case; the
  workaround is of course to remove it (and really 'register' has been redundant
  for years)

The preprocessed file is attached below.

In fact, Ben Hutchings just came up with a minimal test case:

1432:tbm@bigsur: ~] cat > test.c
struct s { int i, j; };
struct s f() { struct s result = {}; return result; }
int main()
{
    register struct s dummy;
    dummy = f();
}

1433:tbm@bigsur: ~] gcc-4.1 test.c
test.c: In function ‘main’:
test.c:6: error: address of register variable ‘dummy’ requested
zsh: exit 1     gcc-4.1 test.c
1434:tbm@bigsur: ~] gcc-4.0 test.c
1435:tbm@bigsur: ~]


Whereas it works on i386:

(sid)1092:tbm@deprecation: ~/src] gcc-4.1 test.c
(sid)1093:tbm@deprecation: ~/src]
