Very strange, I just tried the same plugin on the same IDA and IDA SDK version on linux and it keeps throwing 50420 errors and instantly crashes IDA … Apologies for the spam, I’m just incompetent. Had one variant of the plugin in .idapro and one in the plugin directory of IDA, whereas one variant was two weeks old.
Indeed, there are limitations of the decompiler that hinder decompilation of 256 and 512 operands. We will try to remove them for the upcoming IDA 9.3
Meanwhile, we will send you the fixes for thr hrtng plugin that are necessary as well to avoid interrs.

Please have a look at my lifter – it’s well beyond the capabilities of the lifter in hrtng 
I already support some AVX-512 primitives.

Thank you! When time permits, we will implement the necessary logic in the decompiler. Your lifter will be handy meanwhile, thank you very much!
