That sounds like the behaviour that was initially seen that prompted the
fix.  I don't think that 2.95.3/4 were safe when I tested back then,
contrary to Seth's experiences.

See http://marc.theaimsgroup.com/?l=linux-xfs&m=99535721111774&w=2 for a
description as to what the compiler's doing wrong and why it had to be
un-inlined.
