Segmentation fault in llvmir2hll due to insufficient stack space

Hi. Running retdec under Windows Server 2016, getting this:
```
...
-> converting function_7ca104() ( 2052.13s )
-> converting entry_point() ( 2052.13s )
Running phase: removing functions prefixed with [__decompiler_undefined_function_] ( 2053.03s )
decompile.sh: line 947: 5356 Segmentation fault $LLVMIR2HLL "${LLVMIR2HLL_PARAMS[@]}"
Error: Decompilation of file '/c/retdec/bin/myfile.c.backend.bc' failed
```
myfile.exe can be downloaded here: https://www.dropbox.com/s/jm7xnxtto3r4jxf/myfile.zip?dl=0

Please, help!

Start by reproducing the failure on Windows Server 2016 with the supplied myfile.exe and inspect the llvmir2hll invocation in decompile.sh, especially the generated myfile.c.backend.bc. Determine what exhausts the available stack during conversion and verify that decompilation completes without the segmentation fault.
