I'm probably hitting the same segfault. Here's the stack trace, in case it helps debugging:

@codewiz could you post your OS and compiler version as well?

jdm commented 7 years ago

My suspicion is that this may have been fixed by https://github.com/servo/heapsize/pull/81. Could you update to 0.4.0 and check?

codewiz commented 7 years ago

This is Fedora 25, and I'm building with rust nightly: rustc 1.19.0-nightly (978d2cfee 2017-05-10) cargo 0.20.0-nightly (cf17c9f71 2017-05-09)

rphmeier commented 7 years ago

Preparing an update of our heapsize dependency. For now it's possible this could be worked around by using stable rust.

codewiz commented 7 years ago

Thank you for the speedy fix!

Confirming that downgrading to rust 1.17.0 stable made the crash go away. I'll wait until the heapsize fix gets picked up in smallvec before switching back to nightly.

rphmeier commented 7 years ago

@codewiz Sorry, I still have to patch this in to various other dependencies and finally integrate them into Parity before this issue will be resolved.

NikVolf commented 7 years ago

@codewiz feel free to switch to latest master with nightly rust
