--- Comment #2 from Jacek Caban jacek@codeweavers.com --- Created attachment 69036 --> https://bugs.winehq.org/attachment.cgi?id=69036 patch
conhost itself is not attached to any console in Windows sense, so it does not get the treatment by kernelbase and is terminated, causing termination of its clients, even if they handled the exception themselves. The attached patch fixes it for me. We can just ignore the signal in conhost.
