xTimeComposer-13: global unsafe pointer to interface?

[jerryXCORE]

I compiled the example of "simple web server" in xTimeComposer 14 successfully!
But I failed to compile the same program in xTimeComposer 13.

Then I found the error comes from global unsafe pointer to interface, for example

Code: Select all

extern client mii_if * unsafe xtcp_i_mii;

void xtcp(chanend xtcp[n], size_t n,   client mii_if ?i_mii,        ...)
{
   ....
    unsafe {      xtcp_i_mii = (client mii_if * unsafe) (&i_mii);    }  //This cause compiling error!!!
    ...
  }

And the error message from xTimeComposer-13:

Code: Select all

...
xcc1: internal compiler error

Any hint to make it work? or just don't use global unsafe pointer to interface in xTimeComposer 13?
