As-bytes conversion to EO, does it work?

[MikhailLipanin]

I have a simple program:

[] > app
  QQ.io.stdout > @
    QQ.txt.sprintf "result is %d\n"
      -1.times 228

I covert it to xmir using Syntax.java, and I get:

<objects>
   <o abstract="" name="app" pos="0">
      <o base=".stdout" name="@">
         <o base=".io" >
            <o base="QQ"/>
         </o>
         <o base=".sprintf">
            <o base=".txt" >
               <o base="QQ"/>
            </o>
            <o base="string" data="string">result is %d\n</o>
            <o base=".times">
               <o base="int" data="bytes">FF FF FF FF FF FF FF FF</o>
               <o base="int" data="bytes">00 00 00 00 00 00 00 E4</o>
            </o>
         </o>
      </o>
   </o>
</objects>

After that I convert it Again to eo via XMIR.java and I get the strange result instead of -1:

[] > app
  QQ
  .io
  .stdout > @
    QQ
    .txt
    .sprintf
      "result is %d\n"
      18446744073709551615
      .times
        228

@MikhailLipanin I think it's a bug in XMIR class. @Graur can you please take a look?

[Graur]

@yegor256 Sure, I will check it

[MikhailLipanin]

@Graur, Can you fix this one? Because of this, I can't run this test. There is -1.times x

[yegor256]

@Graur any updates here?

[Graur]

@MikhailLipanin @yegor256 I added test from the issue and XMIRTest.java test passed. This test compare two EO files before and after converting it to XMIR and back to EO. You can check it here: #2083.
