    Description

      Tested with Xbox patches on top of 0.4.15-dev-5051-g0eb042b74cc.

      Entered debugger on first-chance exception (Exception Code: 0xc0000005) (Page Fault)
      		 
      Memory at 0xFFFFFFFF could not be accessed
      		 
       
      		 
      kdb:> bt
      		 
      Eip:
      		 
      * <ntdll.dll:5422 (dll/ntdll/ldr/ldrinit.c:503 (LdrpInitializeThread))>

      kdb:>

      This didn't happened before with bootcd, guilty commit is found. See the comments where I also described behavior changes. It's possible to workaround the problem by using 128 MB of memory. Also the problem seems to be reproduced only on GCC build.

      Live CD boots fine, without problems. Debug logs are attached.
