Xcode Internal Error - Uncaught Exception - Attempt to allocate *** bytes for CFString Failed

I am having a bit of a frustrating Monday morning. I started working in my Xcode project and decided to test a minor change I had made to the code, on my iPad 2.

The code compiles fine, but every time it gets to the "installing" stage, I get the spinning beach ball and then my memory gets eaten up until I get the Internal Error message pop-up.

Here's a screenshot: Internal Error Message

I am completely stumped as to why I am now getting this. Here is the Console log:

5/2/11 11:29:52 AM  Xcode[1251] [MT] Uncaught Exception:

Alright, after a long and stressful day of troubleshooting, I figured it out (sort of). As Oscar Hierro pointed out, this is a problem with the iPad 2. One reason it took me so long to narrow it down to this, was I never even suspected that AN APPLE DEVICE would be causing this issue.

For all who are interested, these are the steps I took to resolve this:

(In the order I performed these in)

—Reinstalled The SDK ~ Didn't Help

—Deleted Xcode preferences ~ Didn't Help

—Tried Numerous Projects. All had similar results.

—Deleted Xcode preferences, and cached files. ~ Didn't Help

—Uninstalled the Dev Tools via Terminal and reinstalled the SDK. ~ Didn't Help

—Got discouraged and nearly gave up. ~ Didn't Help

—Decided to stop testing on the iPad 2. ~ Finally Helped

So what a colleague finally suggested was that we close all apps running in the background (multi-tasking). To my great surprise, it worked! So I can't tell you why this was happening, but I can tell you that closing all the apps on the iPad 2 fixed the problem.

As a side-note, my iPad 2 is running 4.3.2—the latest iOS at this time. I would love to read any thoughts someone might have of why this seemingly fluke bug was happening.

I'm having the same problem, also since yesterday Monday, and it is definitely related to the iPad 2. If I disconnect the device, Xcode works fine, but as soon as I connect it again Xcode starts using more and more CPU and memory until it eventually crashes. The issue doesn't seem to happen when I connect an older iPad (1st gen).

I'm updating my iPad 2 from 4.3.1 to 4.3.2 as I write this. Will see if that fixes the issue (somehow I doubt it).
