Hi. A couple of questions:

• What IDA version do you use?
• What version of the RetDec IDA plugin do you use?
• What version of RetDec do you use?
• Does it fail for all files that you try to decompile or only for the reported one? If only for the reported one, could you please attach it so we can try to reproduce the issue?

• IDA Version: 7.0
• v0.7
• v3.2
• Different error for another test, Test 2
  No longer produces the "Unfinished decompilation was KILLED !!!" log

Edit: I have fixed my problem, I was missing a file from the original retdec files.

Could you please attach the input binaries that you are trying to decompile? You can zip them and upload them here via Attach files in the comment box.

Has this fixed both of the problems that you have reported or just the one?

[s3rvac]

Just a guess concerning the originally reported issue: Did you run multiple decompilations at the same time?

This has fixed both problems, and yes I did run multiple decompilations at the same time.

Unfortunately, the plugin currently does not support multiple simultaneous decompilations. Once you run a second decompilation, the first one gets automatically killed.

I am marking this as closed since the issue was resolved for you.

I created an issue to support multiple decompilations - #35. This is however not a priority right now, since it would be quite difficult to implement and we have some serious problems even with a single decompilation.
