Exception in case of overlapping instructions

[GoogleCodeExporter]

What seems to be the problem?
baksmali raises a java.lang.RuntimeException if an instruction overlaps the end 
of a try block.

What is the exact smali/baksmali command that you ran?
java -jar baksmali-1.3.3.jar -o output classes.dex

What version of smali/baksmali are you using? What rom are you working
from?

What is the airspeed velocity of an unladen swallow?
roughly 11 meters per second

Please provide any additional information below: error messages, symptoms,
etc.
Such an overlapping is not usual for normal applications but can occur in case 
of bytecode obfuscation.

If you need more infos about this, i can provide a writeup about this 
obfuscation technique

Thanks for reporting this.

Just to confirm, dalvik is able to load/run such a dex file? (I assume so, it 
would be a pretty poor obfuscation technique otherwise!)

Yes, you can run it on phones as well as emulators.

Forgot to mark this as fixed when I fixed it :)
