Unfortunately, I haven't found any answeres to this post.

This problem seems to be back with strace 4.3 and kernel 2.4.3. In this
case, which one should be fixed??

Thanks!!

Use the strace source from the ia64_0 branch on
cvs.strace.sourceforge.net.

I've been using it for some time, but it is not up to date with the
latest strace release (4.3). Anyway, your answer means that the problem
is probably with strace itself. Attached is a patch I've used to build
it.

Thanks!!
