Building for debugging...
/home/kali/Fuzz/fuzzilli/Sources/Fuzzilli/Lifting/WasmLifter.swift:595:55: error: cannot call value of non-function type 'Int'
        let numDefinedTablesWithEntries = self.tables.count { instruction in
                                                      ^

    The Array.count with a predicate function was added in 6.0.x1, are you sure you compiled with 6.0.3?
    (I ran into the same issue when the change landed and updating to 6.0.3 fixed the compile error.)

    As a workround you could replace the code in question with:

     let numDefinedTablesWithEntries = self.tables.filter { instruction in
    !(instruction.op as! WasmDefineTable).definedEntryIndices.isEmpty
}.count

    1. Unfortunately the Swift documentation doesn't seem to document this. ↩
