freebsd stable - Jul 2017 - 11.1-RC2 breaks wine, creates unkillable process

After upgrade from stable (r319967) to RC-2 (r320783) wine stops working.

The process gets stuck before there is any console output. It uses 100% 
CPU and is not killable.

I'd guess the stack guard changes broke wine, but I haven't done any 
investigation yet.

The wine package was built by poudriere on 11.0.

Same here on -CURRENT r320620. r319481 (I think) was working fine.

I'm using the i386-wine-devel package from the official repository.

Cheers,
Jan
