Summary
Fixes an issue where continuation names appeared incorrectly when debugging with SOS (Son of Strike debugger extension).
Problem
When using SOS to inspect continuation objects, the names were displayed with incorrect values. For example:
However, the internal MethodTable structure showed the correct name:
Root Cause
The
PrintContinuationNametemplate function inasynccontinuations.hwas using raw pointer types (CGCDesc*andCGCDescSeries*) to access GC descriptor information. These raw pointers don't work correctly in DAC (Data Access Component) scenarios where the debugger needs to read memory from a different process.Solution
Replaced the raw pointer types with their DAC-aware
PTR_equivalents:CGCDesc*→PTR_CGCDescCGCDescSeries*→PTR_CGCDescSeriesThese
PTR_types properly handle address translation when accessed from the debugger, ensuring that continuation names are read and displayed correctly in SOS.Changes
