Bisected it and found 1.7.7 works and 1.7.8 does not. Nothing in the 1.7.8 change overview seems likely.
Also found the source is available. 'NXWin' looks like it fits in the X11 build tree and is a more-or-less typical X application. So the solution, when it becomes important is to recompile it. Still curious if anyone can think of what X related change in 1.7.8 might have caused the breakage. Also if anyone knows a reason why running the 1.7.7 and 1.7.16 DLLs simultaneously would cause trouble. ----- $ ldd NXWin.exe ntdll.dll => SysWOW64/ntdll.dll (0x773e0000) kernel32.dll => syswow64/kernel32.dll (0x76340000) cygwin1.dll => cygwin1.dll (0x61000000) ADVAPI32.DLL => syswow64/ADVAPI32.DLL (0x76a90000) RPCRT4.dll => syswow64/RPCRT4.dll (0x761b0000) Secur32.dll => syswow64/Secur32.dll (0x74f00000) cygz.dll => cygz.dll (0x6e0a0000) cyggcc_s-1.dll => cyggcc_s-1.dll (0x6f810000) GDI32.dll => syswow64/GDI32.dll (0x76a00000) USER32.dll => syswow64/USER32.dll (0x76050000) SHELL32.DLL => syswow64/SHELL32.DLL (0x75280000) msvcrt.dll => syswow64/msvcrt.dll (0x75e50000) SHLWAPI.dll => syswow64/SHLWAPI.dll (0x766e0000) -- 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
