simple.erl example does not work

[tisba]

I just noticed that the example is broken on master. I'm on OS X 10.10.4, using Erlang/OTP 17 [erts-6.4].

With the current master (5570a5a) I get the following error when running examples/simple.erl:

Runtime: 4.250542secs 2352641.14553rps
escript: exception error: bad argument
  in function  hdr_histogram:print_csv/1
     called as hdr_histogram:print_csv(<<>>)
  in call from simple_erl__escript__1437__226631__273844:main/1 (./examples/simple.erl, line 26)
  in call from escript:run/2 (escript.erl, line 752)
  in call from escript:start/1 (escript.erl, line 276)
  in call from init:start_it/1
  in call from init:start_em/1

0.2.6 seems to be fine though.

Hi Sebastian.

Thanks for spotting and reporting this. It looks like some fixes to internals for better NIF resource
tracking has broken the print and other functions as a side effect. Use the 0.2.6 tag for now and I'll
fix the issues on master before dropping tag 0.2.7, which should be soon...

Cheers,

Darach.

Great. I also noticed btw, that the CSV export in elixir works fine, despite the comment and warning in examples/simple.exs. I'm looking forward to 0.2.7!

Fixed in v0.3.0 but worth updating to v0.3.1 for some OOM / SIGSEG fixes.

Cool, thanks! I opened a PR (#28) to fix the Elixir example.
