SubjectRe: 2.4.9-ac12 - problem mounting reiserfs (parse error?)

Hmm, I'm not versant with gdb (strace is the extent of my sophistication),
so I'll try your suggestion below.

It seems that the reiserfs option parsing in 2.4.9-ac12 is foobar, as any
one of "rw,suid,dev,exec,auto,nouser,async" in the options field in
/etc/fstab causes the mount to fail. Also, mounting an r5-hashed reiserfs
file system with the option string "hash=r5" gives this fine error:

REISERFS: Error, r5 hash detected, unable to force r5 hash

I can confirm that the following option strings give a successful mount:
"conv", "hashed_relocation", "notail". I didn't feel like going through
all the options possible.

Is everybody seeing this, or is specific to something about my setup, e.g.
gcc version 3.0.2 20010905 (Red Hat Linux 7.1 3.0.1-3)? I'll try
recompiling with gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-97.1)
to check that.

Cheers, Wayne
