Hi,
I have an issue where the "date" command (from coreutils 8.26-2) hangs.  This is running it with no arguments from a bash script.It has only happened maybe 6 times over several years.  This is on Windows 10 64-bit with cygwin 3.1.4 x86-64.
No idea how to reproduce.  Workaround or other tips appreciated.  It hangs forever (or at least for a few hours) and must be killed (Ctrl+C in shell doesn't work).I've attached a redacted cygcheck output.  
Here are the stacks of the 3 threads within the date.exe process while it is hung:Thread 1:ntoskrnl.exe!KiSwapContext+0x76ntoskrnl.exe!KiSwapThread+0xbfdntoskrnl.exe!KiCommitThreadWait+0x144ntoskrnl.exe!KeWaitForSingleObject+0x255ntoskrnl.exe!KiSchedulerApc+0x397ntoskrnl.exe!KiDeliverApc+0x2e8ntoskrnl.exe!KiSwapThread+0xc98ntoskrnl.exe!KiCommitThreadWait+0x144ntoskrnl.exe!KeWaitForSingleObject+0x255ntoskrnl.exe!NtWaitForSingleObject+0x10bntoskrnl.exe!KiSystemServiceCopyEnd+0x28ntdll.dll!NtWaitForSingleObject+0x14KERNELBASE.dll!WaitForSingleObjectEx+0x93cygwin1.dll!feinitialise+0x1df98cygwin1.dll!feinitialise+0x1e050cygwin1.dll!feinitialise+0x4edbcygwin1.dll!strtosigno+0x513acygwin1.dll!_main+0x253cygwin1.dll!secure_getenv+0x44e6cygwin1.dll!setcontext+0x59dcygwin1.dll!sigfillset+0x35c7cygwin1.dll!secure_getenv+0x488dntdll.dll!RtlpExecuteHandlerForException+0xfntdll.dll!RtlDispatchException+0x219ntdll.dll!KiUserExceptionDispatch+0x2ecygwin1.dll!dlerror+0x820cygwin1.dll!dlerror+0x1101cygwin1.dll!dlerror+0x113dcygwin1.dll!cygwin_dll_init+0x4aecygwin1.dll!setprogname+0x3d53cygwin1.dll!setprogname+0x3e04
