LLDB沒有在正確的行設置斷點

Question

這應該服務器來說明問題。我本來想在Xcode中設置斷點，但指出了同樣的問題發生在我將它們LLDB的命令行：

(lldb) list /Users/jim/Code/breakout-juce/Source/BalLGame.h:300 
    300   } 
    301  } 
    302 
    303  void handleCollision(const Object & other) override 
    304  { 
    305   if (other.getComponentID() == "paddle") 
    306   { 
    307    auto & paddle = dynamic_cast<const Paddle&>(other); 
    308 
    309    auto positionInPaddle = paddle.getLocalPoint(this, getLocalBounds().getCentre()); 
    310    auto normal = paddle.getNormal(positionInPaddle.getX()); 

現在讓我在行設置斷點305

(lldb) break set -f /Users/jim/Code/breakout-juce/Source/BalLGame.h -l 305 
Breakpoint 4: where = Buzz`Ball::getDamage() const + 12 at BalLGame.h:341, address = 0x00000001000018ac 

但開溜 - 它現在是在行341

這是行341：

(lldb) list /Users/jim/Code/breakout-juce/Source/BalLGame.h:340 
    340 
    341  int getDamage() const { return damage; } 
    342 
    343  void tick() override 
    344  { 
    345   setBounds(getBounds().translated(getDirectionVector().x, getDirectionVector().y)); 
    346   angle += deltaAngle; 
    347  } 
    348 
    349  bool isKilled() override { return killed; } 
    350 

我們有調試符號：

(lldb) script lldb.target.module['/Users/jim/Code/breakout-juce/Builds/MacOSX/build/Debug/Buzz.app/Contents/MacOS/Buzz'].GetNumCompileUnits() 
19 

任何想法，接下來要檢查什麼？這是一個調試版本...我剛剛升級到最新的Xcode版本，但它在Xcode 6中的失敗方式也完全相同。

Answer 1

嘗試將Xcode升級到最新版本，如果您使用Xcode 7。1或以下可能有很多錯誤我使用的Xcode 7.1.1並沒有任何問題

Answer 2

如果您設置一個源代碼行不產生任何可執行代碼的斷點（例如評論，一個#ifdef'ed out行，一個永遠不會被使用的非導出函數）lldb會將斷點移動到生成可執行代碼的下一個源代碼行，這可能在另一個函數中。

無法從源素材中確定，但如果getDamage是handleCollision之後的下一個函數，那麼如果沒有爲handleCollision發出代碼，則會解釋斷點運動。如果你這樣做：

(lldb) image lookup -n ClassName::handleCollision 

，或者如果你想諮詢的東西外LLDB：

$ nm <Binary> | grep handleCollision 

？他們居然顯示有該功能的符號？
