[erlang-bugs] Segfault on Erlang VM

[yoshiyuki kanno]

Hello

I'm getting some segfaults on some Erlang VMs while I have tested
LeoFS(http://www.leofs.org) that is a distributed file sytem written
in Erlang.
I could reproduce this issue on a LeoFS cluster with specific
workroads, but it's difficult to reproduce and survey for others.
So I tried to make reproducable code as minimum as possible and put
codes, environments, how to reproduce, backtrace when segfault occured
into below gist.

- Case1: Segfault in case using file:pread

- Case2: Segfault in case constructing Binary
https://gist.github.com/mocchira/2dc016c2c0630b95821b

Please let me know if you have any questions.

BR.
