task '<unknown>' has overflowed its stack

[mytrile]

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 '<unknown>' has overflowed its stack
[1]    14646 illegal hardware instruction  ./target/demo

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

Rust - rustc 0.12.0-nightly (d64b4103d 2014-09-26 21:47:47 +0000)
OS - Mac OSX 10.9.5 (13F34)

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

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
