XCode 3.2.1 crashes on startup on OSX 10.6.2

Question

I have uninstalled it via the devtools uninstall command and reinstalled 3 times to no avail. This all started when I downloaded iphone_sdk_3.1.3_with_xcode_3.2.1__snow_leopard__10m2003a.dmg from the DEV portal and installed.

I've trashed my com.apple.xcode.plist file, uninstalled all xcode plugins as well as Growlcode and I still can't solve this.

Here is the error information:

Answer 1

Get the first argument to dlopen. This probably points to a corrupted file. You can do this with gdb.

$ gdb /Developer/Applications/Xcode.app/Contents/MacOS/Xcode
(gdb) run
... program will hopefully crash ...
(gdb) bt
(gdb) f N                [where N is the highest numbered 'dlopen' frame]
(gdb) p (char *)*($esp)  [I think... can't test now, I'm on PPC]
