Included LLDB segfault when SBTypeSynthetic.IsClassCode is called #1031

Open chase opened 8 months ago

chase commented 8 months ago

OS: Pop!_OS 22.04 LTS Linux VSCode version: 1.70.1 CodeLLDB version: 1.10.0 Compiler: Ubuntu clang version 14.0.0-1ubuntu1.1 Target: x86_64-pc-linux-gnu Thread model: posix Debuggee: C++, trivial example

Included version of LLDB segfaults when running a Python script that calls IsClassCode. This does not crash on LLDB 15.0.7 that I installed through my package manager.

Code under debug (test.cc):

#include <string_view>
#include <unordered_map>
#include <string>
#include <iostream>
std::string g_s;
std::unordered_map<std::string,std::string_view> g_m;
int main() {
    g_s = "hello";
    g_m.emplace("world", g_s);
    std::cout << g_s << g_m["world"];
}

Compiled with: clang++ --std=c++20 test.cc -o simple-ex

Example script

import lldb

def find_synths(debugger):
    original_category: lldb.SBTypeCategory = debugger.GetCategory("cplusplus")

    if not original_category:
        print("C++ category not available")
        return

    for i in range(original_category.GetNumSynthetics()):
        synthetic: lldb.SBTypeSynthetic = original_category.GetSyntheticAtIndex(i)
        specifier: lldb.SBTypeNameSpecifier = (
            original_category.GetTypeNameSpecifierForSyntheticAtIndex(i)
        )
        if not specifier.IsValid():
            continue
        name = str(specifier.name)
        if not name:
            continue

        modified_typename = name.replace("std::__1", "std::Cr").replace(
            "std::__[[:alnum:]]+", "std::Cr"
        )

        if name == modified_typename:
            continue

        if synthetic.contains_code:
            print(name, "Contains code")
            continue

def __lldb_init_module(debugger, internal_dict):
    find_synths(debugger)

Switching CodeLLDB to use my local lldb causes this to no longer crash:

@vadimcn Is the source available for your LLDB fork? I'd like to fix this for you, if possible. It would help my team since it doesn't require additional setup on their part if the pre-built binaries for LLDB work out of the box.

It's in this branch. However, since you are having this problem with c++ code, I think it's likely that it exists in the mainline lldb-16 as well.
