Hello everybody!
We are using Python 3.7 running at CentOS 7 x64. Python is used as a library to create dynamic extensions for our app server.
Some time ago we began to experience crashes in decimal module in some heavy-multithreaded scenarios. After some testing and debugging I was able to reproduce it without our own code using only pybind11 library to simplify embedding (in real app we are using boost.python).
I've built python 3.8 with clang 7 and address sanitizer enabled and got error "use-after-free" with some additional data.
Please find attached C++ source file, python module and ASAN output. Is it really a bug (most probably - data race) or there is something wrong with such embedding scenario? |
