Update all CMakeLists.txt, Makefiles, meson.build, setup.py, and documentation files to use C++17 standard. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Requirements
clang with fuzzer support(-fsanitize=fuzzer. at least clang 8.0 should work)
Status
Currently no open issue found by fuzzer. (except for third party library, especially stb_image)
Setup
Ubuntu 18.04
$ sudo apt install clang++-8
$ sudo apt install libfuzzer-8-dev
Optionally, if you didn't set update-alternatives you can set clang++ to point to clang++8(if your clang version is less than 8.0)
$ sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-8 10
$ sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-8 10
How to compile
$ CXX=clang++ CC=clang meson build -Db_sanitize=address
$ cd build
$ ninja
How to run
Set input size and run fuzz main.
$ ./fuzz_tinyusdz -max_len=128m
for fuzzing fuzz_intcoding_decompress, capping max memory is required(otherwise oom happens).
(Currently fuzz_intcoding_decompress does HARD limit of compressed data up to 2GB)
Use -rss_limit_mb=8192(or more if you encounter oom and have enough memory) to limit memory usage.
$ ./fuzz_intcoding_decompress -rss_limit_mb=8192 -jobs 4
PoC and regressesions
