wslbridge2 segfault #328

Closed godlygeek closed 1 year ago

godlygeek commented 1 year ago

After upgrading my WSL today using wsl --upgrade, I can no longer run wsltty for any distribution. If I run C:\Users\mwozniski\AppData\Local\wsltty\bin\mintty.exe --hold=always --WSL="Ubuntu-20.04" so that the wsltty window doesn't immediately disappear, I see /bin/wslbridge2: Segmentation fault.

I see that a wslbridge2.exe.stackdump has appeared in my USERPROFILE directory, containing:

Oh! I seem to have had two different wsltty installs, in different paths. Turns out the upgraded one installed by chocolatey is working fine, and the segfault only occurred with the other, older install.
