IndexOutOfRangeException in tracing infrastructure when build is running ILC while ETW is enabled #88081
Description
Recently I've been collecting some regressions/improvements for a JIT change that involves running lots of benchmarks with tracing enabled in the background while I do my regular work. I've noticed two times now the following exception during a normal ./build.cmd of the runtime, while a benchmark was running with tracing enabled:
EXEC : error : Index was outside the bounds of the array. [C:\dev\dotnet\runtime\src\coreclr\tools\aot\ILCompiler\ILCompiler.csproj]
System.IndexOutOfRangeException: Index was outside the bounds of the array.

For posterity, the exact command I am invoking BDN with in dotnet/performance micro benchmarks was
