Invalid solc compilation : is it a correct error message?

[sunbeomso]

OS / Environment

Host OS: Ubuntu 18.04.2

Manticore version

0.3.3 (from docker image)

Python version

3.6.9 (from docker image)

Summary of the problem

Manticore reports Invalid solc compilation, none of the solc versions provided worked, although contracts can be actually compiled by the provided solcs.

Step to reproduce the behavior

Let test.sol be a contract from:
https://etherscan.io/address/0x580c1e3caca14826976b5820947f7ad486ac174d#code

My command was:

sudo docker exec CONTAINER manticore /tmp/test.sol --contract BitcoinAgileToken --core.timeout 1800 --solc-solcs-bin solc-0.4.25 --core.mprocessing single --core.procs 1 --exclude delegatecall,reentrancy,reentrancy-adv,env-instr,ext-call-leak,suicidal,uninitialized-memory,uninitialized-storage,unused-return

Again, I checked that this contract can be compiled with solc 0.4.25.

Expected behavior

If contracts can be compilable by some solcs, then they should be successfully analyzed by Manticore with those solcs.

Actual behavior

Although the contract above can be compiled with solc 0.4.25, Manticore produces a message Invalid solc compilation, none of the solc versions provided worked.

However, if I provided an option --solc-solcs-bin solc-0.4.16 (after installing solc-0.4.16), Manticore successfully works.

Any relevant logs

Hi @sunbeomso, thank you for reporting this issue.

Can you confirm that solc-0.4.25 is a binary in the PATH? What happens if you run

solc-0.4.25 /tmp/test.sol

[sunbeomso]

Hi @montyly ,

1. sudo docker exec CONTAINER_NAME solc-0.4.25 --version outputs:

solc, the solidity compiler commandline interface
Version: 0.4.25+commit.59dbf8f1.Linux.g++

2. sudo docker exec CONTAINER_NAME solc-0.4.25 /tmp/test.sol outputs several warning messages but no error messages:

        require(this.balance >= amount * sellPrice);      // checks if the contract has enough ether to buy

Finally, I remark that, for this contract, I resolved the issue by providing an options with different solcs:

--solc-solcs-bin solc-0.4.26,solc-0.4.25,solc-0.4.24,solc-0.4.23,solc-0.4.21,solc-0.4.20,solc-0.4.19,solc-0.4.18,solc-0.4.17,solc-0.4.16,solc-0.4.11

However, I still encountered the similar situations for a few other contracts.

My point is that the produced warning message seems not correct in that the contracts can be compiled with the provided solcs.

Thanks for the details @sunbeomso.

Most likely it's an issue with crytic-compile, the library that handles solc compilation.

I can't reproduce the issue locally, could you share how the container was created? If you can't share the container, could you try the following commands:

$ sudo docker exec CONTAINER_NAME manticore test.sol --solc solc-0.4.25 --contract BitcoinAgileToken
$ sudo docker exec CONTAINER_NAME crytic-compile --version
$ sudo docker exec CONTAINER_NAME crytic-compile test.sol --solc solc-0.4.25
$ sudo docker exec CONTAINER_NAME crytic-compile test.sol --solc-solcs-bin solc-0.4.25

[sunbeomso]

@montyly

[1] sudo docker exec CONTAINER_NAME manticore //tmp/test.sol --solc solc-0.4.25 --contract BitcoinAgileToken

With the command above, Manticore successfully begins analysis without error messages.

[2] $ sudo docker exec CONTAINER_NAME crytic-compile --version outputs 0.1.6.

[3, 4] Both commands (sudo docker exec CONTAINER_NAME crytic-compile //tmp/test.sol --solc solc-0.4.25 and sudo docker exec CONTAINER_NAME crytic-compile //tmp/test.sol --solc solc-0.4.25) outputs the same following warning messages:

I can't reproduce the issue locally, could you share how the container was created?

I created the container as follows (which seems there is no unusual part for me):

1. sudo docker create --entrypoint=/bin/bash --name CONTAINER -it trailofbits/manticore:0.3.3

2. sudo docker start CONTAINER

3. Copy solc v. 0.4.25 from my local to the container (assume my solc v 0.4.25 is located in /usr/local/bin/solc_0.4.25):

sudo docker cp /usr/local/bin/solc_0.4.25 CONTAINER:/usr/bin/solc-0.4.25

4. Run manticore after copying test.sol (which is mentioned above) from my local to the container:

sudo docker cp test.sol CONTAINER:/tmp/test.sol

sudo docker exec CONTAINER manticore /tmp/test.sol --contract BitcoinAgileToken --core.timeout 1800 --solc-solcs-bin solc-0.4.25 --core.mprocessing single --core.procs 1 --exclude delegatecall,reentrancy,reentrancy-adv,env-instr,ext-call-leak,suicidal,uninitialized-memory,uninitialized-storage,unused-return

I can't reproduce the issue locally,

Could you try my steps described above?

I have just tried again my steps above without any modifications, and I double-checked that I still encounter the error message Invalid solc compilation.

Of course, sudo docker exec CONTAINER solc-0.4.25 /tmp/test.sol outputs warning messages but no error messages.

[sunbeomso]

@montyly Hi, could you tell me about the progress of this issue?

With the latest Manticore (v.0.3.4), I still encounter problems (Manticore produces Invalid solc compilation messages for contracts that can be compiled with provided solcs).
