local IT person. For some shops with very knowledgeable technical staff,
that may be acceptable.

If you look at the linux kernel for instance, all fixes are released in
patches and support the older kernels for backward compatibility.

The issue is not the _intentions_ regarding compatibility.

The question was "who ensures the patch does not break...". The
average single contributor does not have the resources to test a
patch in all environments, particularly on large SMP machines with
particular hardware devices. In some cases we are talking machines
that cost in excess of a million dollars.

A company that has machines in excess of million dollars would have a
IT department that would do testing, alot of open source projects come
out of real work enviroments, they are not all made at home in
somebodies spare time(thats a bad misconception of open source), ibm,
sun to name two have released different open source projects.
