Bun keep crashing when run Opencode on Windows (Bash) #750
pr i mentioned above just merged and will be available in canary soon and Bun v1.2.19. if you run into any further issues don't hesitate to open another issue and let us (bun) know :)
Reacted by Abdias Joel Moya Perez and Martin Solev
I used to see a couple of those with previous versions, but as of 0.15.13 is't all good. win11/amd64 with both wezterm and ms-terminal-preview -- works fine.
@stellar-ssj you should prolly downgrade then, is this a constant issue for you?
yeah i am going to downgrade back to where i was, unfortunately 1.0.39 has rendered OC useless for me - nothing really works, tool calls are broken, constant aborts and syntax errors, the UI gets messed up if i scroll.. its bad.
