[.NET6 fix port] AccessViolationException with PublishSingleFile #81181
Description
Description
I am requesting a port of the fix for issue #62145 from PR #74389 for .NET 6 since it is the LTS release. I confirmed that changing from .NET 6 to .NET 7 fixes the problem in a test application but cannot migrate all applications to .NET 7 at this time.
This bug is impacting me specifically when using the New Relic Agent in Docker when targeting .NET 6 and using the .NET 6 runtime image (mcr.microsoft.com/dotnet/runtime:6.0) but goes away when targeting .NET 7 and using the .NET 7 runtime image (mcr.microsoft.com/dotnet/runtime:7.0). When running containers in the 6.0 configuration it will sporadically throw the AccessViolationException (about 1-2% of the time) but never on the 7.0 configuration.
Reproduction Steps
I copied the reproduction example from the previous issue and tested it in both .NET 6 and .NET 7 by just changing the TargetFramework from net6.0 to net7.0 and was able to reproduce the issue only in .NET 6 using the most recent (6.0.13) runtime with the fix working in .NET 7.
using System.Diagnostics.Tracing;
namespace SegFaultTest
{
internal class Program
{
static void Main(string[] args)
{
EventListener eventListener = new MyEventListener();
Console.WriteLine("Press any key to abort...");
// Do some stuff
for (int i = 1; i < int.MaxValue; i++)
{
if (Console.KeyAvailable)
{
break;
}
string a = new('a', i % 10000);
}
Console.WriteLine("Done.");
}
}
internal class MyEventListener : EventListener
{
protected override void OnEventSourceCreated(EventSource eventSource)
{
if (eventSource.Name.Equals("Microsoft-Windows-DotNETRuntime", StringComparison.Ordinal))
{
EnableEvents(eventSource, EventLevel.Informational, (EventKeywords)1);
}
}
protected override void OnEventWritten(EventWrittenEventArgs eventData)
{
Console.WriteLine($"Event written {eventData.EventId,3} {eventData.EventName ?? string.Empty}");
}
}
}
Expected behavior
No AccessViolationException thrown
Actual behavior
AccessViolationException is thrown
Regression?
No response
Known Workarounds
Upgrade to .NET 7
