stack_overflow-4.py output depending on the compiler and compiler flags. gcc -O3 (./configure): --- test_python_call: 11904 calls before crash, stack: 704.1 bytes/call test_python_iterator: 17460 calls before crash, stack: 480.0 bytes/call test_python_getitem: 245760 calls before recursion error, stack: 0.2 bytes/call => total: 275124 calls, 1184.3 bytes per call --- It's better than stack memory usage in 2017: https://bugs.python.org/issue30866#msg297826 clang -O3 (./configure CC=clang): --- test_python_call: 10270 calls before crash, stack: 816.1 bytes/call test_python_iterator: 14155 calls before crash, stack: 592.0 bytes/call test_python_getitem: 245760 calls before recursion error, stack: 0.3 bytes/call => total: 270185 calls, 1408.4 bytes per call --- clang allocates a little bit more memory on the stack than gcc. I didn't try PGO or LTO yet. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46600> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
