Follow these steps :

1) Find the command line that is used to build PCH file. Note down the  
include prefix header files used to build PCH.

2) If there is a -include switch on failing command line pointing to a  
PCH file (or directory) then remove it.  (Sometimes developers  
#include <blah.pch>)

3) Add -include command line switch to include prefix header file from  
step 1)

4) Reproduce the crash. Now, PCH is out of equation.
