IMPORTANT

  1. You have verified that the issue to be present in the current dev branch.
  2. Please supply the command line options and relevant environment variables,
    e.g., a copy-paste of the contents of out/default/fuzzer_setup.

Thank you for making AFL++ better!

Describe the bug
I successfully compiled Python 3.13.0 using both Clang 14 and GCC without any issues. However, when attempting to compile it with AFL++'s afl-cc and afl-c++, the make process fails, reporting memory leak errors. I'm uncertain whether this is a result of an issue with AFL++'s compilation process or if there's another underlying cause.

To Reproduce
Steps to reproduce the behavior:

  1. git clone [email protected]:python/cpython.git
  2. ./configure CC=/home/liyuweiheng/fuzzers/AFLplusplus/afl-cc CXX=/home/liyuweiheng/fuzzers/AFLplusplus/afl-c++
  3. make

Expected behavior
Successfully compiled.

[-] FATAL: forkserver is already up, but an instrumented dlopen() library loaded afterwards. You must AFL_PRELOAD such libraries to be able to fuzz them or LD_PRELOAD to run outside of afl-fuzz.
To ignore this set AFL_IGNORE_PROBLEMS=1 but this will lead to ambiguous coverage data.
In addition, you can set AFL_IGNORE_PROBLEMS_COVERAGE=1 to ignore the additional coverage instead (use with caution!).

Thank you, I've tried this parameter and it works. However, I find this memory leak quite strange. Should I report this as a bug to Python? I'm using clang 12 with aflplusplus 4.09a in asan mode, and it's still triggering a memory leak. I've also been able to reproduce the memory leak when compiling Python with a Docker image. The same issue occurs with afl++ versions 4.04c, 4.07c, and 4.08c.

the leak is in python, so it happens with any afl++ version ;-)
not all leaks are a problem. most are not actually.
in a simple program eg.:
void main() ( char *x=malloc(1); }
this will report a leak, but it would be no issue. only if x is lost or overwritten it would be.

Thank you for your response. I have found how to enable ASan in Python. Memory leaks usually do not cause problems.
./configure --with-address-sanitizer --without-pymalloc
During the compilation process, you need to setexport ASAN_OPTIONS='detect_leaks=0:allocator_may_return_null=1:handle_segv=0'
