Segfault with BEAM 19 / Elixir 1.3.2

[zweizeichen]

Hi, eflame:apply fails for me with a segmentation fault on BEAM 19 (only tested on macOS) when executing a very simple Elixir script. As my knowledge of Erlang is quite limited, I could not confirm the issue directly in Erlang. It would be great if you could take a look at this. Thanks!

Console output:

mix run [1] 97810 segmentation fault mix run

Version info:

Erlang/OTP 19 [erts-8.0.2] [source] [64-bit] [smp:8:8] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Nice catch! Could you try including a stack trace of a segfault? (e.g. while running beam inside lldb)

Here you go - I hope it helps :)
