Xcode build & run "innocent" (?) problem

I am testing my game on my iPhone (3GS and UnityPro), so:

I build & run in Unity,

I build & run in Xcode,

Xcode Installs the app on my iphone and I get the message:

GDB: Program received signal: "EXC_BAD_ACCESS"

The game stays idle in the splash screen. However, if I terminate Xcode, it asks me:

Stop tasks before closing? Unity-iPhone Project:"Unity-iPhone.xcodeproj"Target:"Unity-iPhone",

I press OK and Xcode terminates. The game also terminates (from just displaying the splash screen actually) and If I start it manually from my iPhone, it runs without a problem.

I was wondering if this trouble is innocent or I should do something to stop it from occurring, even though It doesn't give me a real problem (from what I can tell till now).
