    Description

      After a upload of 11.8.5 to Debian I noticed the ppc build failed with this result mismatch:

      main.analyze_stmt_prefetch_count         w4 [ fail ]
              Test ended at 2025-12-08 13:00:14

      Later in the same run a retry passed, so it was sporadic:

      main.analyze_stmt_prefetch_count         w4 [ retry-pass ]   3274
      

      Reporting this as a data point in case others see this pattern repeat.
