Well, it points to nothing ;) The bug here is that probably
job_new links the allocated memory into some global list or so,
so it's not about initializing the memory but the fact that it
_is_ aliased by other things.

Yes, we can probably give a few examples of what is not appropriate
use of 'malloc'.

Do you think I should revert the patch on the branch nevertheless?
(it was a fix for a missed-optimization regression only ...)
