Crash with latest version and OTel export

[mmarczell-graphisoft]

If I create a brand new SwiftUI app with Xcode, and initialize Embrace SDK 6.15.1 the following way, using opentelemetry-swift 2.2.1, both from SwiftPM:

import EmbraceIO
import OpenTelemetryProtocolExporterCommon
import OpenTelemetryProtocolExporterHttp
import SwiftUI

@main
struct swiftui_ios_sandboxApp: App {
    init() {
        do {
            let otelConfig = OtlpConfiguration(
                exportAsJson: false
            )
            let otel = OpenTelemetryExport(
                spanExporter: OtlpHttpTraceExporter(
                    endpoint: URL(string: "https://opentelemetry.my-company.com/v1/traces")!,
                    config: otelConfig
                ),
                logExporter: OtlpHttpLogExporter(
                    endpoint: URL(string: "https://opentelemetry.my-company.com/v1/logs")!,
                    config: otelConfig
                )
            )
            
            let embrace = try Embrace.setup(options: Embrace.Options(export: otel)).start()
        } catch let e {
            print("Error starting Embrace \(e.localizedDescription)")
        }
    }
    
    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}

I get a crash on launch at this line:

https://github.com/open-telemetry/opentelemetry-swift/blob/8ab241c09c5daa2ad21cc8445fb881020c99608c/Sources/Exporters/OpenTelemetryProtocolCommon/trace/SpanAdapter.swift#L56

with the error message Fatal error: Negative value is not representable

It seems to me that the problem is that the hydrateSpan function at

embrace-apple-sdk/Sources/EmbraceOTelInternal/Trace/Tracer/Span/Processor/EmbraceSpanProcessor.swift

Line 211 in 2d10aff

attributes[SpanSemantics.keySessionId] = .string(sessionId)

inserts a new attribute but doesn't update the totalAttributeCount
