What seems to be the problem?
When smaling, I got this output:

UNEXPECTED TOP-LEVEL EXCEPTION:
java.lang.IllegalStateException: Cannot get the location of a label that hasn't 
been placed yet.
        at org.jf.dexlib2.builder.Label.getLocation(Label.java:54)

        at org.jf.smali.main.main(main.java:229)

I know it's my fault, but there isn't any detailed information, like caused by 
which file and the line number, so I can't fix it.

What is the exact smali/baksmali command that you ran?
java -jar smali-2.0.3.jar . -o classes_mod.dex

What version of smali/baksmali are you using? What rom are you working
from?
smali 2.0.3 (also tried 2.0.2), baksmali 2.0.2, any ROM with Dalvik.

What is the airspeed velocity of an unladen swallow?
... Can't understand

Please provide any additional information below: error messages, symptoms,
etc.
Nothing more.

I think it simply means that one of your labels hasn't been defined yet, but 
you are using it in a conditional already.

Although it would be nice to know where the error is, you may have to comb 
through it manually..

Yes, but it is such a huge task that I think computers will do it better.

@lacoursiere18: That is a different problem. You shouldn't be getting that 
error after disassembling with no changes. Are you sure there are no changes in 
that file?

The problem in this issue is that there is no context associated with the 
error. But your error clearly has the line and number as context.

Just as an update on this issue, the main problem is that the label resolution 
stuff is happening later, and doesn't have access to the original context (file 
and line) where the labels were created. So I've been thinking of how to 
improve the situation here. I could throw a quick fix in for this one problem, 
but I want to fix it in a more systemic way.
