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?
