That shouldn't happen. For some reason, we're inserting the /lib directory into the list of bind-mounted sub-directories twice.
I'll take a look at this later today. We will need to fix up the integration with the intern projects anyways.
Thanks, if it depends multiple library so files in different folder, all of them will be inserted to /lib?
libuv example also has same error
$ ./helloworld

Any update ? The curl is a good example to start
I use the #81 and there has another error

Hey there, I just commited the fix for the futex failure (fb1822b). The duplicate /lib issue turned out not to be the root cause.
libuv is next up on my mental todo list.
