Hi again,
i'd like to provide additional information. described behavior can be
reproduced on multiple different machines. i tried it on following
setups:
2.4.27-2-386 [debian kernel],
2.6.11 [custom build kernel],
2.4.27 [debian kernel],
2.6.11.9 [custom build]
all computers have file 4.12-1 installed.
it was tested on computers with Xeon, P4, Celerons, AMD Athlon CPUs.
i attach whole log from strace.
