valgrind-numpy-scipy.supp

# Valgrind suppression file for NumPy & SciPy errors and leaks in pybind11 tests
#
# On updating a dependency, to get a list of "default" leaks in e.g. NumPy, run
# `PYTHONMALLOC=malloc valgrind --leak-check=full --show-leak-kinds=definite,indirect python3.9-dbg -c "import numpy"`
# To use theses suppression files, add e.g. `--suppressions=valgrind-numpy-scipy.supp`
