32-on-64 doesn't build on Fedora due to glib2-devel.i686 conflicting
with its x86_64 cousin, so I can't reproduce this.  Can you try
bisecting this further?

$ git tag M b195043003d90ea4027ea01cc7a6c974ac915108
$ git bisect start M M^
...
$ git merge --no-commit M^
[build and test]
$ git merge --abort (or git checkout -f)
$ git bisect [good|bad]

if it happens that M^2 was the bad commit, you'll get a merge conflict. 
In that case do

$ git merge --abort
$ git merge M

(you'll just be testing M again, but it's good to verify)
