[PATCH 1/1] shell32: Introduce combine_path helper for DDE.

[Marvin]

Hi,

It looks like your patch introduced the new failures shown below.
Please investigate and fix them before resubmitting your patch.
If they are not new, fixing them anyway would help a lot. Otherwise
please ask for the known failures list to be updated.

The tests also ran into some preexisting test failures. If you know how
to fix them that would be helpful. See the TestBot job for the details:

The full results can be found at:

Your paranoid android.

I didn't mean for this to be a separate MR, just a separate commit in the original MR.

[Alex Henrie (＠alexhenrie)]

Sorry, I thought you meant that the allocation cleanup alone would be more likely to be accepted than the sanitization code, which would have meant that it needed a separate MR. I just updated the original MR to have both commits.
