New submission from Arcadiy Ivanov: Around line 1480 of configure.ac: if test "$Py_DEBUG" = 'true' ; then # Optimization messes up debuggers, so turn it off for # debug builds. if "$CC" -v --help 2>/dev/null |grep -- -Og > /dev/null; then OPT="-g -Og -Wall $STRICT_PROTO" else OPT="-g -O0 -Wall $STRICT_PROTO" fi else OPT="-g $WRAP -O3 -Wall $STRICT_PROTO" fi
The "-Og", unfortunately, optimizes too much resulting in local variables and arguments being optimized out: (gdb) info locals kwlist = {0x7ffff02c3318 "database", 0x7ffff02c3321 "timeout", 0x7ffff02c3329 "detect_types", 0x7ffff02c3336 "isolation_level", 0x7ffff02c3346 "check_same_thread", 0x7ffff02c3392 "factory", 0x7ffff02c3358 "cached_statements", 0x7ffff02c336a "uri", 0x0} database = 0x7ffff04f7da0 ":memory:" detect_types = 0 isolation_level = 0x1 factory = 0x7ffff04c7dc0 <pysqlite_ConnectionType> check_same_thread = 1 cached_statements = 4888694 uri = 0 timeout = 5 (gdb) info args self = <optimized out> args = 0x7fffeff6be28 kwargs = 0x0 When "self" is optimized out it's too much optimization for debug mode. ---------- components: Build messages: 285505 nosy: arcivanov priority: normal severity: normal status: open title: --with-pydebug optimizes too much versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29279> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
