Describe the bug

Description
A System.AccessViolationException occurs when running an ASP.NET Core application on Huawei Kunpeng (ARM64) using .NET 8. The crash consistently happens during the application startup phase, specifically during configuration binding and logging initialization.

Error Message & Stack Trace

Fatal error. System.AccessViolationException: Attempted to read or write protected memory.
at System.Globalization.NumberFormatInfo.get_CurrentInfo()
at System.Int32.TryParse(ReadOnlySpan s, Int32& result)
at Microsoft.Extensions.Configuration.ConfigurationKeyComparer.Compare(String x, String y)
...
at Microsoft.Extensions.Hosting.HostApplicationBuilder.Build()
at Program.

$(String[] args)

Environment
.NET SDK/Runtime: 8.0
Architecture: ARM64 (AArch64)
CPU: Huawei Kunpeng 920
OS: Kylin Server V10 SP3

Observed Behavior
The application fails with a fatal AccessViolationException when the ConfigurationKeyComparer attempts to parse a string to an integer, which calls into NumberFormatInfo.get_CurrentInfo().

Additional Context
The issue seems related to how .NET 8 interacts with the system's ICU library on this specific ARM64 platform.
Temporary Workaround: Setting DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 is not resolving the issue.

Expected Behavior

The application should start normally without memory access violations.

Steps To Reproduce

Create a standard ASP.NET Core 8.0 Web API project.

Deploy and run the application on a Huawei Kunpeng ARM64 server.

The application crashes during builder.Build().

Exceptions (if any)

No response

.NET Version

8.0.6

Anything else?

No response

Looks like this issue should be transferred to dotnet/runtime as it doesn't appear to be specific to ASP.NET Core.

@AlexKuai thanks for the report. Is there a way you can create a debugger for this crash? Sorry, I don't have the environment setup to try it myself. You may try run a simple Console app there too.

Also, could you please confirm if ICU is installed correctly on the Huawei Kunpeng ARM64 server?

Also, could you please confirm if ICU is installed correctly on the Huawei Kunpeng ARM64 server?另外，能否请您确认一下华为鲲鹏 ARM64 服务器上是否已正确安装 ICU？

Thanks for your reply. I tried a simple console program and it worked fine.

I tried a simple console program and it worked fine.

Thanks!
Did you have DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 set when trying the console app? I am checking if you were by passing the ICU loading. And did you have a chance creating a core dump for the crash?
