If we embed Python.Net into DotNet application, it crashes on Linux.
Crash occurs when application exits.
PythonEngine.Initialize();
try
{
using (Py.GIL())
{
dynamic sysModule = Py.Import("sys");
Console.WriteLine("Python engine version:");
Console.WriteLine(sysModule.version);
}
// This workaround reduces risk of Mono crash.
// Problem will be fixed in mono 4.6
if (Type.GetType("Mono.Runtime") != null)
{
Runtime.Py_Main(3, new[] { "/pcfgtest.exe", "-c", "exit" });
}
else
{
// Program will crash if we will try to do this under Windows.
//// Runtime.Py_Main(3, new[] { "/pcfgtest.exe", "-c", "exit" });
}
}
finally
{
PythonEngine.Shutdown();
}This is sample of code that produces crash.
Also it contains 'probably workaround".

Debug info from gdb:
=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
Aborted (core dumped)I tried everything - python 2.7, python 3.5, Mono 4.2, 4.4.
It does not matter, behavior always the same.
Also i tried to build with Py_DEBUG under linux (and pass python library from python3.5-dbg package)
I receive assertions on PythonEngine.Init:
