It allows to even worse stuff. I was just surprised that gcc does that.. and that I did not know about this trap. I was probably telling people to do = {} for structure init... Should we get "= {}" warning for checkpatch? Is it fair to replace "= {}" with memset() as soon as it is returned to userland, without testing that gcc "miscompiles" this particular example?
