Tarantool generates much bigger number of traces than LuaJIT #122
Description
Related to #121
How to reproduce:
Build Tarantool:
git clone https://github.com/tarantool/tarantool/
cd tarantool
CFLAGS="-fsanitize=fuzzer-no-link" LDFLAGS="-fsanitize=fuzzer-no-link" CC=clang CXX=clang++ cmake -S . -B build -DCMAKE_BUILD_TYPE=Debug -DENABLE_FUZZER=ON -DLUAJIT_NUMMODE=2 -DLUAJIT_ENABLE_CHECKHOOK=OFF -DLUAJIT_ENABLE_GC64=ON
cmake --build build/ --parallel
cd build
git clone https://github.com/ligurio/luzer
cd luzer
CC=clang-21 CXX=clang++-21 cmake -S . -B build
cmake --build build/ --parallel
cd ..
Run test with Tarantool: LUA_CPATH='./luzer/build/luzer/?.so;;' LUA_PATH='./luzer/?/init.lua;./test/fuzz/lua-tests/src/tests/lapi/?.lua;;' ./src/tarantool -jdump=Tias ./test/fuzz/lua-tests/src/tests/lapi/bitop_bxor_test.lua -runs=100
Output:
WARNING: Coverage symbols are being provided by a library other than libFuzzer. This will result in a broken Lua code coverage and severely impacted native extension code coverage. Symbols are coming from this library: ./src/tarantool
INFO: Running with entropic power schedule (0xFF, 100).
