Short description of error
Attempting to use the Bridge edge tool with the following edges (https:*i.imgur.com/tyKRsir.png) produces the following result (https:*i.imgur.com/Vv6XSrq.png)
Work Around
Move the inner shell (https:*i.imgur.com/tFPfpp8.png) down slightly to produce intended results (https:*i.imgur.com/tTMt30P.png)
(First bug report, sorry if i did anything wrong)

confirmed on first sight, studying bridge_loop_pair now.
There is already a codepath for exactly this case here , and I have something that doesnt reverse the vert order for this report (but this probably breaks elsewhere... will need thorough testing)
@ideasman42 : easy for you? Please go ahead and claim (I'll claim for the time being and assign to you if I dont get it in a reasonable time...)

The bridge tool always tries to keep the normal consistent.
The mesh normals in the attached file look like this:
So the bridge tool did its best to maintain the new geometry with consistent normals.
You can get the result by inverting the normals of one of the "shells".
From what I see, this is not a bug, but it works as intended.
