Error in analyzying smart contract about securify2

[YannisSach]

It seems like a bug in the compiler which is caused by the new line character in line 737 of 0x7_solidity.txt

"\x19Ethereum Signed Message:\n32"

I will try to fix it as soon as possible. In the meantime, you can delete the \n character or replace the string entirely.

Edit: I pushed a fix to the develop branch

I have cloned it and built the docker container. To use the compiler release 0.5.17, how should I do it?

Hi, I tries to use the master branch to analyze some contract... and I receive some errors. One of them is analyzying the 0x36.sol.txt file and I received 0x36.txt results. Do you think that I have to reinstall something or do you already know the reason? Thanks so much
0x36.sol.txt
0x36.txt

This was caused by the usage of staticcall. I pushed a fix to the develop branch.

Hi, I tried to use Securify with some other files receving errors processing attached files (0xf41.sol, 0xdb.sol,0x27.sol)
0x41.txt
0x27.txt
0xf41.txt

I am using solc 0.5.15, python 3.7.
I do the following steps:
To use the develop branch, to run the new one:
$ git clone -b develop https://github.com/eth-sri/securify2.git /home/mirkostad/Programmi/Tools/securify/
I follow thw insatructions
$ virtualenv --python=/usr/bin/python3.7 venv
$ source venv/bin/activate
To go in the home directory of project
$ cd /home/mirkostad/Programmi/Tools/securify/
$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:pwd
$ pip install --upgrade pip
$ pip install -r requirements.txt
$ pip install -e .

Then I launched:
$ securify /home/mirkostad/Programmi/smart-contracts/Mutations/Original/0xf41.sol
receiving...
