default stack size for threads is approx 140k on musl which is fine in most cases but some of python apps e.g. python3-lz4 bindings run into thread stack size overflow. Increase the default size to 2M on musl, glibc defaults to 8M, so we are good there. This default stack size change is limited to interpreter and stdlib modules only, thats why CFLAGS_NODIST instead of CFLAGS Signed-off-by: Khem Raj <raj.khem@gmail.com> --- meta/recipes-devtools/python/python3_3.11.4.bb | 7 +++++++ 1 file changed, 7 insertions(+)
