The recent snapshots with W7 fail somewhat (but the system seems to function more or less), i've got the following message with W7: 0 [main] tcsh 15528 fixup_mmaps_after_fork: VirtualQueryEx failed for MAP_PRIVATE address 0x6FFFFFA0000, Win32 error 5 368 [main] tcsh 15528 D:\Users\dexcoff1\dexcoff1\cyglcl\uxl\tcsh-6.20.00\bin\tcsh.exe: *** fatal error in forked process - recreate_mmaps_after_fork_failed 700 [main] tcsh 15528 cygwin_exception::open_stackdumpfile: Dumping stack trace to tcsh.exe.stackdump 0 [main] tcsh 19080 fork: child -1 - forked process 15528 died unexpectedly, retry 0, exit code 0x100, errno 11 No more processes. I had a look into sigproc.cc and noticed that recently (commit 69cc7a068656b5c6ef07ca079a213f801e02e650, dated 2019-01-27, DUPLICATE_SAME_ACCESS has been replaced by 0 in a call to DuplicateHandle(). I switched it back, re-compiled and the fork problem above disappeared. Don’t know the impact on W10. HTH.
