When I link the test with host system's glibc, it do not fail although
it's also a PowerPC 64 bits binary. So I can reasonably think the test
is correct and should complete successfully. It's true syscall don't
fail (no error returned) but at the same time it seems to do absolutely
nothing (file size don't change). As as said I don't understand why the
code in lines 42 and 44 seems to be executed twice. Is it related to
some macro expansion ?

I already looked over google and bugzilla before posting here and did
not find any other report of this problem. I don't think I'll file a new
bug as it seems to be very specific to my build and I didn't test it
against latest cvs version.

This was the only test that failed and it's not really a critical
function. Moreover calling the function produces no error. So I guess
I'll try to live with it hoping it will not become a serious issue
later.

Anyway thank you for your help and suggestions.

Cheers,
Renaud.
