Program.cs

using System.Diagnostics;

var procStartInfo = new ProcessStartInfo()
{
    FileName = "/bin/bash",
    Arguments = "yes",
    UseShellExecute = false,
    RedirectStandardOutput = true,
    RedirectStandardError = true,
};

using var proc = new Process() { StartInfo = procStartInfo,  };

try
{
    Console.WriteLine("ffs");
    proc.Start();
    Console.WriteLine("yeaaaaa");
}
catch (Exception e)
{
    Console.WriteLine(e.ToString());
}

Crash happens on Start() method invocation.

Works then I run it without debugger, it passes executes normally (outputs what it should in this case).

This library is affected by this issue as well, because it uses underlying System.Diagnostics.Process too.

        using System.Text;
        using CliWrap;

        var stdOutBuffer = new StringBuilder();
        var stdErrBuffer = new StringBuilder();

        await Cli.Wrap("date")
            .WithStandardOutputPipe(PipeTarget.ToStringBuilder(stdOutBuffer))
            .WithStandardErrorPipe(PipeTarget.ToStringBuilder(stdErrBuffer))
            .ExecuteAsync(ct);

        var stdOut = stdOutBuffer.ToString();
        var stdErr = stdErrBuffer.ToString();
        
        if(stdOut.Any())_l.LogInformation(stdOut);
        if(stdErr.Any())_l.LogError(stdErr);

Works when .NET is at older 7.0.11

Thank you for reporting this issue. This was fixed by #90826. The fix is included in .NET 8 RC2.
