-noINL and -check c lead to internal compiler error `Assertion "(actual_cls != C_scl) && (formal_cls != C_scl)" failed`

When compiling

use Array: all;

int[n:shp] myrotate ( int[n] rv, int[n:shp] a)
{
    return { iv -> a[mod(iv - rv, shp)] | iv < shp};
}

int main ()
{
   res = myrotate( [], 42);

   return res;
}

with sac2c -noINL -check c we get
