R devel - Jun 2007 - How to set R_CStackLimit

Hi,
 
I have tried to disable stack checking by set R_CStackLimit to -1. However,
it always crashes my win32 multiple threads program. I am using R-2.5.0. My
code looks like:
 
#include <Rversion.h>
#if (R_VERSION >= R_Version(2,3,0))
#define R_INTERFACE_PTRS 1
#define CSTACK_DEFNS 1
#include <Rinterface.h> 
#endif
 
and then, add below line to my main function:
    R_CStackLimit = (uintptr_t)-1;  //crashes when step to this line.
 
As for input library in link option, I only link to Rdll.lib. Am I missing
something?
 
Thanks very much!

First, Rinterface.h is not installed on Windows, so you must be using a 
header from within the R sources.  You do so at your own peril!

R_CStackLimit is only described in a Unix-specific section of 'Writing R 
Extensions'.  The description there and Rinterface.h is designed for Unix 
compilers, not for Windows compilers.  Since R_CStackLimit is a variable 
exported from a DLL, many Windows compilers will need it declared as a 
dllimport.  You have not told us your compiler (but 'Rdll.lib' is not
part
of R and not needed for the recommended MinGW).  If (as I guess) it is 
Visual Studio, you need to heed the comments in README.packages about 
this.
