Sorry, looks "a bit" more complex. And quoting you "Confirmed. I'd
classify this as a fairly serious bug. I am currently testing the
following fix."

I can confirm that Red Hat 7.3 latest gcc errata fixes (issued 13
months later) indeed generates correct code for at least
__ntfs_init_inode() with Randy's .config file. The compiler version,

% gcc --version
2.96

Oops, not to talkative considering how heavily patched ...

% rpm -qf =gcc
gcc-2.96-113

gcc generated code from Mandrake 9.1 RC2 is also ok.

% gcc --version
gcc (GCC) 3.2.2 (Mandrake Linux 9.1 3.2.2-2mdk)
