hello andrei and dimitry,
(dimitry, thats a cool email address).
so i started creating a VM for you guys to reproduce the bug, and found out
it works great on t2.large aws instances - but crashes consistently on
c5.large aws instances, which i think explains why you couldn't reproduce
it...
dimitry's test fails on the c5.large, and succeeds on the t2.large (rest of
the tests you requested, pass on both). output attached. (i had to add sudo
and change protobuf-python -> python protobuf).
pypy crashes after restore on my personal laptop as well, but unfortunatly
the tests didn't run on my laptop, output exception and cpuinfo also
attached.
i'm creating a VM for you guys on AWS with a c5.large instance type to work
on, will send connection details later on a private email.
i'm using the following ami, at eu-west-1 aws region
"ami-0741d47e" #
ubuntu/images/hvm-ssd/ubuntu-artful-17.10-amd64-server-20180102
i'll also finish writing a script to reproduce the issue, and will send you
the instructions in that email.
thanks you very much,
Shlomi.
