Fix ABIEncoder V2 compilation failures

[cgewecke]

cf: solidity 10354

@dileepfrog discovered a way to configure the optimizer so stack too deep errors go away without stripping out the trace.

config.compilers.solc.settings.optimizer.enabled = false;
config.compilers.solc.settings.optimizer.details = {
  yul: true,
  yulDetails: {
    stackAllocation: true,
  },
};

TODO

• Check behavior across solc versions

Still same error !! Any help ?

[washboardalex]

The above config change did not work for us, we are still experiencing this issue with compiler v0.7.5 and abi encoder v2.

@amalnathsathyan @washboardalex You will need to make these changes to the solidity-coverage code itself, which overrides your project settings. For example, Float-Capital@723ed39#diff-21d7978b20ae71148e42ff520f3a63e74edba221f9285763d67eb1735d42fdbfR111

In 0.7.17 this special config is available as a boolean option.

Will test it out ... if everything seems okay will make this default in 0.8.x

To turn it on, use .solcover.js to set

configureYulOptimizer: true

[cgewecke]

In 0.7.18 you can additionally specify any optimizer details via a .solcover.js config option. Have also added a little section to REAMDE FAQ docs with other configurations known to work.

There's not much more we can do about this I think (unfortunately)
