Hi,
I've just compiled and tested curl 8.12 and have an Access violation related to c-ares.
This issue was not present on 8.11.1
⏩ use case :
curl -v https://www.google.com/
and
<?php curl_exec(curl_init("https://www.google.com/")); ?>
✅ when compiling with -DENABLE_ARES=OFF: all works
🔴 when compiling with -DENABLE_ARES=ON : I have this exception
