> I have determined that bug #27571 was introduced on November 19, 2016 with commit c61ee94959ba96b2a327df0684593f7e569e30be.  The following patch to the Emacs 26 branch as of today (01/08/2018) reverses the commit

That commit was a merge commit, and installed all sorts of changes. The patch 
you sent reverses just part of the commit. It'd be helpful to know the original 
commit that caused the problem, as opposed to the later merge.

Also, the patch undoes some fixes, such as integer overflow checking, that we'd 
like to keep. This is another reason that it'd be helpful to know the original 
commit. Alternatively, it'd be helpful to know why the patch fixes the bug, so 
that we can keep that part of the patch without discarding other fixes from the 
source.
