So I made change to create new `DwarfParser` > instance everytime in `LinuxAMD64CFrame::sender`. I think this looks good, makes sense, the native DwarfParser has its own context. So the existing reuse of dwarf as nextDwarf at old line 150 might be unwise! I see that getNextCFA, called down at new line 168, handles nextDwarf being null. ------------- Marked as reviewed by kevinw (Reviewer).
