from hyper.

Could you run them with RUST_BACKTRACE=1 RUST_LOG=hyper=debug and paste
the results?

When I create new cargo project and try to run the server from the
examples directory it gives me this error after successful compilation:

task '' has overflowed its stack

Same thing when I run the benchmarks in the hyper project repo

Hm, useless. Could you try running in gdb?

[seanmonstar]

Hm, I'm getting it now also. Will dig in.

It seems the implementation of read on Box<NetworkStream> is recursing until overflow. Something in rustc must have changed regarding how it derefs.

I wonder if it's related to this: rust-lang/rust#17464
