update: the problem is the count[a]++; 

workaround without -version=v_ICE below:

// https://issues.dlang.org/show_bug.cgi?id=15817
module bugs.bug_D20160320T235820;
import std.string;
import std.array;

int fun(string b){
  auto targets=b.split.array;
  uint[string]counts;
  foreach(a;targets){
version(v_ICE){
  counts[a]++;
} else{
  auto ptr=a in counts;
  if(ptr)
*ptr=*ptr+1;
  else
counts[a]=1;
}
  }
  return 0;
}

void fun2(){
  enum a=`a1.a2 b1.b2`;
  static int b=fun(a);
}

Dustmited test case:

S[] split(S)(S s)
{
size_t istart;
S[] result;

foreach (i, c ; s)
result ~= s[istart .. i];
return result;
}

int fun(string b)
{
auto targets = b.split;
uint[string] counts;
foreach (a; targets)
counts[a]++;
return 0;
}

void fun2()
{
enum a = `a1`;
static b = fun(a);
}
