Done. No conflicts. Setup run fine, problem is not solved. Observation: Cygwin errors appears more often than Msys2 errors. Even got initial loading on incorrect address: child_info_fork::abort: T:\cygwin64\bin\cygman-2-7-5.dll: Loaded to different address: parent(0x190000) != child(0x3FB700000) > It's likely the Insider debug builds dynamically enable/disable > features and functions or run alternate system DLLs which gather > info by acting as BLODAs. > MS can mess around with your systems to enable new stuff (possibly > in different combinations) and see which systems they cause problems > on. > Hopefully they can also dynamically revert new releases causing > problems. > Your systems are the canaries for their Continuous Delivery QA. > > Make sure you continously back up any work on those systems and > don't ignore warnings, especially build expiries (you are meant > to be allowed 3 reboots after expiry before the buildrefuses > to boot!) Thanks! Not sure that situation is just "test" or "temporary". I'm using prerelease track so this can go to release. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
