I pointed out that this code is not C standard compliant but it occurred in
customer application that should be ported to x86 platform. This bug is not
issued by gcc and very hard detected. Customer has more then 2000 such patterns
in its application and he is not sure that all such patterns were found. So I
still assume that we should fix it for x86 platform. Note also that icc does
not have such issue.
