Hello!
I noticed that some programs that depend on zlib stopped working and started creating stackdumps with Windows Dev Channel build 20246.1. I could not get gdb working with zlib but I figured a workaround: I recompiled zlib with cygport using the latest gcc (10.2.0) and copied the dll over the old one. That did fix the problem.
Regards,Teemu

Hi Teemu,
Could this have been a BLODA caused by your AV package e.g. Windows Defender?
Some utilities e.g. Tortoise <VCS> also install DLL intercepts that can break
Cygwin, so you have to drop them from Cygwin PATH.
Do you happen to know the zlib version you were running?
You can check under your local package directory:
$ ls -t $PACKAGE/x86*/release/zlib/zlib0/
zlib0-1.2.11-1.tar.xz zlib0-1.2.8-3.tar.xz zlib0-1.2.8-1.tar.bz2
zlib0-1.2.7-1.tar.bz2 zlib0-1.2.5-1.tar.bz2

Hi Brian,

I have had Cygwin installed for a long time now on and it has worked on every Dev Channel version until now. The only that that changed was an upgrade to a new version. I have excluded Cygwin's directory in Windows Defender settings.

Zlib is version 1.2.11-1.
