GDB 7.12 worked fine (codesigned) on macOS 10.11.

On macOS 10.12, it fails miserably with "During startup program terminated with signal ?, unknown signal."

Checked certificate and codesigning status, nothing changed.

Rebuilt from SourceForge, reinstalled/resigned, nothing changed.

Disabled SIP, nothing changed.

Looks like a macOS bug to me. Any ideas?

I fortunately did not upgrade my MAC, just tested it in a Fusion partition. I will be rejecting Sierra until it's fixed.
