STINNER Victor <[email protected]> added the comment:
The crash start to occur with a Python callstack depth larger than 750. It
doesn't crash with setrecursionlimit(750). See attached stack.py. Example:
vstinner@freebsd$ ./python stack.py 750 10240
setrecursionlimit(750)
stack_size: 10240.0 kiB = 10.0 MiB
end of main thread
It seems like calling _thread.stack_size(s) doesn't help:
vstinner@freebsd$ ./python stack.py 1000 10240
setrecursionlimit(1000)
stack_size: 10240.0 kiB = 10.0 MiB
Segmentation fault (core dumped)

I see different options:
* Reduce the Python recursion limit in the test
* Find a way to increase the default thread stack size on FreeBSD
* Skip the test on FreeBSD
On macOS, configure.ac uses a stack of 8 MiB:
# Issue #18075: the default maximum stack size (8MBytes) is too
# small for the default recursion limit. Increase the stack size
# to ensure that tests don't crash
# Note: This matches the value of THREAD_STACK_SIZE in
# thread_pthread.h
LINKFORSHARED="-Wl,-stack_size,1000000 $LINKFORSHARED"
