After upgrading to Windows 10 TH2 (ver 1511, build 10586), any attempt to launch a cygwin64 process from 32bit native app (for example, C:\windows\syswow64\cmd.exe) *always* results in a fork error.
To be precise, I can execute 64bit bash.exe from 32bit cmd.exe. However, this bash process never succeeds in forking a child (ls or something). Also, I cannot launch 64bit mintty.exe from 32bit cmd.exe. It always fails in a error dialog saying that: mintty: could not detach from caller Try '--help' for more information. When launching from 64bit app, this issue doesn't happen. -- 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
