ios5 - Xcode 4 gcc failure on Archive build: skips precompile step? (also after cleanup)

Question

as many others i face the problem that my xcode (4.3.2) tells me:

 cc1obj: warning: /Users/myname/Library/Developer/Xcode/DerivedData/Foo-afikuaovoaeqhreaaaakpafseuuv/Build/PrecompiledHeaders/Foo_Prefix-guqixmujoiaaaacwjctfkrztxmbz/Foo_Prefix.pch.gch: created by a different GCC executable
 cc1obj: error: /Users/myname/Library/Developer/Xcode/DerivedData/Foo-afikuaovoaeqhreaaaakpafseuuv/Build/PrecompiledHeaders/Foo_Prefix-guqixmujoiaaaacwjctfkrztxmbz/Foo_Prefix.pch: No such file or directory
 cc1obj: error: one or more PCH files were found, but they were invalid

When i want to Debug my Application via inspector. Building and running the app in development works fine, release also breaks it.

now the common tricks were to clean my build folder ( + alt key .. ) or deleting the derived-data folder entirey. both done, no effort.

any information i can provide the get some help? :)

Cheers.

这可能听起来很疯狂，但最近发生了类似的事情（不完全相同）。我最终实际上删除了finder中的Derived Data文件夹 - 在清理之后 - 并且为我解决了它。
