Environment model simplifications can break error traces
For instance, when I switched off CIL merging for module "drivers/hwmon/dme1737.ko" of Linux 3.14 checked against "linux:fs:sysfs" I got the following exception:
Raise exception: Traceback (most recent call last): File "/home/novikov/work/klever/core/core/components.py", line 118, in run self.main() File "/home/novikov/work/klever/core/core/utils.py", line 95, in callbacks_caller ret = attr(*args, **kwargs) File "/home/novikov/work/klever/core/core/vrp/__init__.py", line 225, in fetcher raise self.__exception File "/home/novikov/work/klever/core/core/vrp/__init__.py", line 341, in process_single_verdict error_trace = et.import_error_trace(self.logger, witnesses) File "/home/novikov/work/klever/core/core/vrp/et/__init__.py", line 38, in import_error_trace envmodel_simplifications(logger, trace) File "/home/novikov/work/klever/core/core/vrp/et/envmodel.py", line 27, in envmodel_simplifications error_trace.final_checks() File "/home/novikov/work/klever/core/core/vrp/et/error_trace.py", line 429, in final_checks self.resolve_function(data[-1]))) ValueError: Unexpected return from function '_tmp_dme1737_abs_paths_trimmed_idme1737_sio_inb' in thread 2, expected last entered function _tmp_dme1737_abs_paths_trimmed_ioutb
Similar exceptions broke processing of 28 of 35 error traces.

I checked it out and saw that without our general optimizations environment model simplifications work well and the witness can be at least visualized. However, the visualization contains suspicious None lines. Evgeny, I propose first you update general optimizations and then revisit the issue.

Let's consider everything related with witnesses in Klever 1.0. I hope that we will at last have a new format and a new printer of witnesses there that will be a great step forward. In particular, this issue can become irrelevant.
