Describe the bug

When trying to compile ProtocolV3TestBase contract using zkforge zkbuild, I'm getting the following error:

Failed to compile smart contracts with zksolc: Compilation failed with stdout: "" and stderr: "Contract `src/ProtocolV3TestBase.sol:ProtocolV3LegacyTestBase` 

compiling error: The contract `src/ProtocolV3TestBase.sol:ProtocolV3LegacyTestBase` assembly-to-bytecode conversion error: assembly parse error 

Label fun_e2eTest was tried to be used for either PC or constant at offset 91848 that is more than `65535` addressable space

The contract `src/ProtocolV3TestBase.sol:ProtocolV3LegacyTestBase` assembly-to-bytecode conversion error: assembly parse error 

Label fun_e2eTest was tried to be used for either PC or constant at offset 91848 that is more than `65535` addressable space\n\n". 

Using compiler: "/path-to-compiler/.zksync/zksolc-macosx-arm64-v1.4.0", with args "/path-to-repo/aave-helpers/src/ProtocolV3TestBase.sol" CommandArgs { inner: ["--standard-json", "--solc", "/path/.svm/0.8.18/solc-0.8.18"] }

Please note running zkforge zkbuild directly on the aave-helpers repository results in the following error as described in issue #285 and #291:

The application panicked (crashed).
Message:  called `Result::unwrap()` on an `Err` value: Error("missing field `contracts`", line: 1, column: 750)
Location: crates/common/src/zk_compile.rs:1164

So to reproduce the error we should delete all contracts in the repo except ProtocolV3TestBase and its dependencies and compile.

@brotherlymite thanks for posting this issue. We will investigate but at first glance looks like the max bytecode limit of the zkevm has been met meaning there may be a need to break up the file for compilation. However, we will investigate further.
