Cygwin Shell Fails to Start when Enabling High Address

[Benjamin Cao]

Hi Corinna,

I have tried the latest snapshot and have confirmed that with AllocationPreference enabled, I can start Cygwin without any crashes.

Thanks,
Ben Cao

A bug in Cygwin.  Actually, 2 bugs, one generic bug and one in 64 bit Cygwin only.

I applied patches to the git repo and I just uploaded new developer snapshots to https://cygwin.com/snapshots/ which contain the fixes.

I'm also creating new test releases 2.2.0-0.4 and upload and announce them later today.

Please give any of them a try, preferredly today, so I may be able to create the offical Cygwin 2.2.0 release today as well.


Thanks,
Corinna
