Martin Panter added the comment: The error message comes from Undefined Behaviour Sanitizer, which was added to newer versions of GCC and Clang. Currently I am compiling with
./configure --with-pydebug CC="gcc -fsanitize=undefined -fno-sanitize=alignment -fno-sanitize=shift" https://gcc.gnu.org/onlinedocs/gcc/Instrumentation-Options.html#index-fsanitize_003dundefined-962 I thought it is worth adding a test for the impossible __length_hint__() value. Since the test iterator returns no elements, there will not be a MemoryError, but if overflow detection is enabled (such as UB Sanitizer or -ftrapv), it is guaranteed to exercise the overflow path and would be detected. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1621> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
