Issue Title

.net core 2 console application stops execution and quits without providing any kind of exception messages, except short notice “Aborted”

General

The issue is only reproducible on Linux, but not Windows.

System:

• Linux: Debian 9, x64 bits
• dotnet --version: 2.1.3
• compiled on Windows 10 x64 with command: dotnet publish -c release -r debian-x64
• thread on StackoverFlow
• bug report on git

Description

During the deserialization (or initialization) of objects of a certain type - application crashes on Linux environment immediately.

A sample code for issue reproduction is:

static void Main(string[] args)
{
     var symbol = Symbol.ONE;
     // if real library is used then Symbol.BNB_BTC or (Symbol)"BNBBTC" will do
}

The Symbol class is implemented with a type-safe Enum pattern:

public sealed class Symbol
{
    public static readonly Symbol ONE = new Symbol(new[] { OrderType.Limit, OrderType.LimitMaker, OrderType.Market, OrderType.StopLossLimit, OrderType.TakeProfitLimit });
    public static readonly Symbol TWO = new Symbol(new[] { OrderType.Limit, OrderType.LimitMaker, OrderType.Market, OrderType.StopLossLimit, OrderType.TakeProfitLimit });
    public static readonly Symbol THREE = new Symbol(new[] { OrderType.Limit, OrderType.LimitMaker, OrderType.Market, OrderType.StopLossLimit, OrderType.TakeProfitLimit });
    // 264 such lines in total

    public Symbol(IEnumerable<OrderType> orderTypes)
    {

    }
}

In the example above, upon initialization of Symbol type object - application would abort at rate 1/5 (or more often/rarely):

Testing

while sleep 0.5 ; do dotnet ConsoleApp1.dll ; done

The linux command will execute dotnet application once in half-a-second time. Therefore, if at least one “Aborted” is printed within 20 second interval - you can consider the test as not passed.

Fix

I was able to come up with a temporary solution which seems to be working at the moment.

If we change an anonymous type of object in constructor parameter list to List - then that will work nicely.

Instead of this:

new[] { OrderType.Limit, OrderType.LimitMaker, OrderType.Market, OrderType.StopLossLimit, OrderType.TakeProfitLimit }

use this:

new List<OrderType> { OrderType.Limit, OrderType.LimitMaker, OrderType.Market, OrderType.StopLossLimit, OrderType.TakeProfitLimit }

Also, it was confirmed, that OrderType[] type of object yields absolutely the same result as new[] Also, it was confirmed (on my machine), that if the number of static properties is halved, then the issue is gone, therefore, for better effect - test the solution when more than 200 Symbols are defined in Symbol class.

Steps to reproduce

The easiest steps to reproduce the issue is to:

1. Download the same library as I did here.
2. Change the source for the Symbol class, so that anonymous object is used (author recently applied a fix, per my request)
3. add new console application (see description section)
4. compile and then run on Linux (see testing section)

If you see the “Aborted” message after some time, then that’s the issue.

Suggested fix

I would appreciate to

1. see some kind of exception message when such errors are thrown
2. issue to be fixed

Rest is up to you. Good luck.
