I'm using Windows Insider (slow ring, prerelease). After recent update to build 14931, cygwin keeps randomly fail on fork. This happens not every fork, but frequent enough. Simplest way to trigger it is to run mandb. At variable delay I got something like child_info_fork::abort: T:\cygwin64\bin\cygman-2-7-5.dll: Loaded to different address: parent(0x3FEAB0000) != child(0x1C0000) Dll name and child address may vary. I updated cygwin to latest version, but problem remains. Exactly the same problem with Msys2, but additionally from time to time I got different error: *** fatal error - cygheap base mismatch detected - 0x1802FE408/0x106E408. This problem is probably due to....
I set variable CYGWIN=detect_bloda, but nothing is detected. What else could I check? Versions: $ uname -srvmo CYGWIN_NT-10.0 2.6.0(0.304/5/3) 2016-08-31 14:32 x86_64 Cygwin $ cat /proc/registry/HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows\ NT/CurrentVersion/CurrentBuildNumber 14931
Run rebase -is to check for DLL conflicts. After the update did you run "rebase-trigger full" and setup, with NO Cygwin processes running, to remap the system DLLs and rebase the Cygwin DLLs? 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!) -- Take care.
