I’ve seen this mentioned twice, but we don’t have an issue open to track. When fixed, --disable-fuzz-binary should be remove from the Windows CI config.
To reproduce:
0make -C depends/ HOST=x86_64-w64-mingw32 NO_QT=1 NO_WALLET=1 NO_UPNP=1 NO_ZMQ=1 -j8
1./autogen.sh
2./configure --prefix=/home/ubuntu/bitcoin/depends/x86_64-w64-mingw32 --disable-wallet --with-gui=no --disable-bench --with-utils=no --with-daemon=no
3make -j8
