--- Comment #8 from oiaohm oiaohm@gmail.com --- 3.2.60+ is patched to have /proc/sys/abi/ldt16. Only 3.12.21 kernel.org mainline is the only LTS that if you are upto date cannot run win16 binaries. Hopefully 3.12.22 release will have all the current LTS kernels sorted. So at 3.12.22 release I will check if it has patch then update faq.
I was wondering why Linux Kernel 2.6.32 was not patching Mid-2014 is its offically end of life. So anyone still running this should be migrating anyhow.
I remembered http://wiki.winehq.org/PreloaderPageZeroProblem This is the prior example of wine running into a Linux secuirty fix. It was also crashing when this first change appeared.
/proc/sys/abi/ldt16 default state is going to be no 16 bit on 64bit kernel.
