PerfView 2.0.72

Roll-up through 2021/09/16.

• Fix crashes from traces containing .NET Alloc data where the object size is reported as 0.
• Fix an issue where non-Windows traces where TraceEvent attempts to detect if a stack frame comes from the kernel.
• Fix SYSTEMTIME argument parsing.
• Allow users to specify the process ID when creating ActivityPath strings.

TraceEvent 2.0.71

Roll-up through 2021/07/26.

• Fix for unresolvable types from mscorlib in allocation traces that use the PerfView CLR profiler implementation.
• Enable stack collection for file queries and directory enumerations.
• Documentation updates.
• Support for .NET 6 GCMarkWithType event changes; if you intend to look at the GCStats view, or use the TraceEvent library to interpret GC events on a trace collected with .NET 6.0 runtime, you will need to upgrade to at least this version of TraceEvent. Previous versions will throw an exception during these operations.
• Fix Directory Enumeration stacks.
