I didn’t find any report about it or in know issues.
When you try to attach the mono into unity project it throw a exception with something like unsupported platform exception (it happens the first time).
In Unity console it keep printing “Failed to wait on a semaphore (Interrupted system call)”
They don’t check for EINTR in their platform semaphore abstraction layer as they should.
Business as usual, really: nobody reads the documentation and then app work or crash depending on the weather on Mars. Unity developers are not first and not last to make that mistake…
I forgot to report her back. But it is working for a while, I think last 2 versions. It show some errors when you attach the process, but it works. I don’t know if they fix or was my mistakes.
