描述

Example: https://delve.teamcity.com/viewLog.html?buildId=27817

For whatever reason it seems that the hardware breakpoint state gets restored somehow on some threads, sometimes, after a hardware breakpoint has been disabled.

研究方向
The issue describes intermittent test failures in the TestWatchpointsBasic test, likely related to hardware breakpoint state restoration. Investigate the test file pkg/proc/native/proc test.go and related hardware breakpoint handling code in pkg/proc/native/. Reproduce the failure using the provided TeamCity build log. Check if there are any known races or missing synchronizations when disabling hardware breakpoints on threads.
