Program terminated with signal SIGSEGV, Segmentation fault

Hi,
I am using ReactJS.net (v5.2.5) with JavaScriptEngineSwitcher.ChakraCore (v3.7.1) in .netcore 3.1 on linux.
My application terminates randomly with Segmentation fault. I don't know much about gdb but running basic commands on the core dump generated by Segmentation fault gives the following output:

> gdb carwaleweb/Carwale.UI core

Please let me know if more info is needed. Or if I should be filing this issue in the ChakraCore repository.

Thankyou.

Hello, Meet!

Are you using an libChakraCore.so assembly from the JavaScriptEngineSwitcher.ChakraCore.Native.linux-x64 package? It's just that this assembly differs from the official one: Tomáš Deml's patch has been applied to it that fixes such errors.

Answer 2 · 2020-09-20T04:16:03.000Z

Yes, I only have the following references related to it, also this happened with 3.7.2 as well

    <PackageReference Include="JavaScriptEngineSwitcher.ChakraCore" Version="3.7.2" />
    <PackageReference Include="JavaScriptEngineSwitcher.ChakraCore.Native.win-x64" Version="3.7.2" />
    <PackageReference Include="JavaScriptEngineSwitcher.ChakraCore.Native.linux-x64" Version="3.7.2" />
    <PackageReference Include="JavaScriptEngineSwitcher.Extensions.MsDependencyInjection" Version="3.3.0" />
    <PackageReference Include="React.AspNet" Version="5.2.5" />

Also lldb output :

/home/consul/carwaleweb/libChakraCore.so

Because the libChakraCore.so assembly is located at the root of web application, and not in the runtimes/linux-x64/native subdirectory, I recommend that you compare this assembly with the assembly from NuGet package.

Answer 4 · 2020-09-20T18:49:55.000Z

This is because it is a self-contained ready to run publish of the application. I'll still compare and let you know. Thanks.

Answer 5 · 2020-09-21T04:17:19.000Z

diff does not show any difference between the file in the nuget package and the file at /home/consul/carwaleweb/libChakraCore.so

Answer 6 · 2020-09-21T07:33:52.000Z

Try deploying a web application with a assembly from the official release.

Answer 7 · 2020-09-23T04:49:25.000Z

I tried deploying the file from the official release by copying the libChakraCore.so file but was unable to run the application with that, is there anything else to be done to use the official release ?

Also I deployed the application without a self-contained build and the frequency of segfaults reduced but it still happened.
Thanks.

Answer 8 · 2020-09-29T09:13:10.000Z

The segfault that occurs in the regular build also gives a similar trace

Let me know how I can help debug this and provide more information. Thanks.

Answer 9 · 2020-09-29T16:53:02.000Z

I am not an expert in C++ and Linux, so it is difficult for me to help you solve this problem.

I can only recommend you to try using the JavaScriptEngineSwitcher.Node module as an JS engine.

Answer 10 · 2020-10-27T14:43:42.000Z

Hello, Meet!

I recommend that you try the experimental cross-platform version of the JavaScriptEngineSwitcher.V8 module.

You can also see my suggestions for improving the original ClearScript library.

Answer 11 · 2020-10-28T10:01:33.000Z

Hi Taritsyn,
We have already started using JavaScriptEngineSwitcher.Node in production and haven't faced any issues yet, also the latencies are comparable. I'll definitely try out the cross-platform version of JavaScriptEngineSwitcher.V8 some time later.
Thanks.
