If debug statements are removed - compiler behave as expected:

$ more d_compiler_bug_around_debug.d
#!/usr/bin/rdmd -debug
import std.stdio;

void main(){
bool dummy_flag = false;
    if( dummy_flag )
        writeln("debug print 1"); 
                writeln( "Some real action ..." );
        writeln("debug print 2"); 
        else{
        writeln( "Some other action ");
     }
}
$ ./d_compiler_bug_around_debug.d
./d_compiler_bug_around_debug.d(10): found 'else' instead of statement
./d_compiler_bug_around_debug.d(13): unrecognized declaration
Failed: dmd -debug -v -o- './d_compiler_bug_around_debug.d' -I'.'

I'm not sure what you're expecting, but the compiler behaves correctly in your
first example.

I am expecting to see somewhat like 

./d_compiler_bug_around_debug.d(10): found 'else' instead of statement
./d_compiler_bug_around_debug.d(13): unrecognized declaration

when compiled with debug key and nothing when compiled without.
I believe my expectations are correct ...

(In reply to comment #3)

 ./d_compiler_bug_around_debug.d(10): found 'else' instead of statement
 ./d_compiler_bug_around_debug.d(13): unrecognized declaration

The following is valid syntax:

debug { } else { }

Although I don't think I've ever wanted to use an else block on a debug
statement.
