:rkraesig, since you are the author of the regressor, bug 1758654, could you take a look?
For more information, please visit auto_nag documentation.

[Ray Kraesig [:rkraesig]]

i686-w64-mingw32-clang++ doesn't seem to be performing the stateless-lambda-to-function-pointer conversion for some reason. This is probably not intermittent.

And of course this didn't show up on mach try fuzzy -q cppunit. Looks like it's revert time again. :|
