When displaying the code signature on Google Chrome 58.0.3029.110 with jtool Sydney, stderr contains the following message:

Unknown opcode 14 - has Apple changed the op codes?Please notify J!


The signatures in Firefox 53.0.3 and VMware Fusion 8.1.1 yield:

Unknown opcode 7375626a - has Apple changed the op codes?Please notify J!


Casual poking on El Capitan does not reveal affected OS binaries.

Thanks for letting me know. I'll get on a fix in the next version (London, coming soon).
