I'm affraid I have one for you :-(

I've just tested both the debian experimental e2fsprogs package, as well as 
manually built package from git 8359f626a4e9, both running on a debian testing 
system with a 3.7.3 kernel from experimental.

In both versions resize2fs corrupts a clean ext4 fs if bigalloc is enabled.

Attaching console output of example run.

Best regards
