Interesting what rustc --version is this with ?

[steveklabnik]

rustc 1.0.0-nightly (6b95d8bed 2015-04-09) (built 2015-04-10)

[dirvine]

yip confirmed with rustc 1.0.0-nightly (d9146bf8b 2015-04-07) (built 2015-04-08)
Happy you ignore that one for now and I will take a peek and push a fix.

[dirvine]

Yes a bug introduced in the read method, I have commented out that for now to let you check out bench and will commit a fix as soon as I figure out the issue. One of the guys working on it now. (frantic pace week :-) )

[dirvine]

weird, bench is OK till rustc --version rustc 1.0.0-nightly (be9bd7c93 2015-04-05) (built 2015-04-06)

[benjaminbollen]

I updated from rustc from build 2015-04-06 to nightly 2015-04-10 and again benchmarks and tests pass. Does it succeed for you on the latest nigthly?

[steveklabnik]

(frantic pace week :-) )

Oh don't I know that feeling

[dirvine]

I bet! All good though

Benchmark tests all pass with current code.
