Stuck at "running CopyPropagationOptimizer" for 10 days

[SamDecrock]

Hi,

RetDec seems to be stuck at some step inside CopyPropagationOptimizer for about 10 days now. It's been stuck at using 5GB of RAM and 100% of CPU. RAM usage does not increase.

The last step it has been showing for over 10 days is:

Warning: [NonRecursiveCFGBuilder] there is no node for an edge to `goto 0x5d40c` -> skipping this edge

What is happening and can I skip this step somehow?

Thanks, Sam

Edit: still the same after 22 days... :-(

I 'solved' it by adding this to the command line:

--backend-disabled-opts=CopyPropagationOptimizer

But it seems like a lot of exe's I'm trying to decompile these days are stuck at this phase... Or could it be coincidence?

Same problem for me. Software crashes after few hours during "CopyPropagationOptimizer". Please find enclosed the dll. You need a least 20 Go of RAM for this file. The crash is clearly an out of memory but I don't think it's fine that this small file needs more than 2 hours to be analyzed.

With --backend-disabled-opts=CopyPropagationOptimizer analyse takes about two minutes.

Before I used that trick I was able to get farther along, but still got hung up in that same step. One time I tried it the memory utilization started to slowly go down to near zero about 2 hours into the decompile process before of course I messed up and killed the script. Never experienced it again after that. What does removing that optimization step effect?
