The foreach loop is not needed, another temporary »works« as well:

---
import std.algorithm;

void main() {
   auto a = 1;
   auto dg = ( uint c ){ return cast( dchar )a; };

   // This works:
   dg( 1 );

   // This crashes:
   map!( ( c ){ return dg( c ); } )( [ 1 ] );
}
---

GDB prints the innermost frame like this:
0x08049846 in ave.main.__dgliteral2!(int).__dgliteral2 (this=0x0, c=1) at
ave.d:11

Note that this is null – could this be an issue, or is this relative to the
current frame?
