What is wrong with precompiled headers and ASLR?

I read it on several sites that precompiled headers and address space layout randomization is incompatible. What makes them incompatible? What would it take to fix it?

My qu开发者_Go百科estion is OS independent I heard this is a problem on linux with grsecurity and on newer windows versions. (And I don't know what else has ASLR.)

Precompiled headers are not incompatible with ASLR.

The particular technique used to implement precompiled headers that was used by older versions of the Visual C++ compiler was broken by ASLR. There is an article on the Visual C++ Team Blog with details on the problem and an explanation of how it was fixed. There is a hotpatch available for Visual C++ 2008 SP1 and the problem is not present in Visual C++ 2010.

There may have been a similar problem on Linux, I don't really know. I'm no expert on Linux, Linux security, or GCC.
