처음 실행시 sos.threads에서 windbg 예외

Question

windbg (x64) 버전 6.3.9600.16384에서 크래시 덤프를로드하고 .net에 sos 확장자를로드하면 처음으로 !threads 명령을 실행하면이 오류가 발생합니다. :

Answer 1

이 확장로드되는 기억 명시 적 작업 공간을 저장하여 발생하는 이상한 문제가 될 것으로 보인다. 내가 .loadby sos clr이고 작업 공간을 저장하면 다음에 작업 공간을 열 때 sos가 두 번로드됩니다. 그러나 내가 .load c:\path\to\sos.dll을하고 작업 공간을 저장하면 다시 열 때만로드됩니다.

요약하면 windbg의 작업 영역은 혼란 스럽습니다.
