pdb.run() seems crashing different positions of Python (Python/ast_opt.c:488 for pdb.run, Python/ast_opt.c:494 for compile()). But the commit 364d0d20f924071b749e5a889eca22628f4892a3, PR 23744, bpo-42609 for compile() also fix this bug in pdb.run(). Should we close this issue and mark it as fixed? $ gdb ./python (gdb) run Python 3.10.0a6 (default, Mar 19 2021, 11:45:56) [GCC 7.5.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> compile("1+2" * 1000000, "-", "exec") Program received signal SIGSEGV, Segmentation fault. 0x000000000063aedc in astfold_expr (node_=0xf5707d0, ctx_=0x7ffff6282450, state=0x7fffffffd608) at Python/ast_opt.c:494 494 CALL(astfold_expr, expr_ty, node_->v.BinOp.left); (gdb) run Python 3.10.0a6 (default, Mar 19 2021, 11:45:56) [GCC 7.5.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import pdb >>> pdb.run("1+2"*1000000) Program received signal SIGSEGV, Segmentation fault. 0x000000000063ac8f in astfold_expr (node_=0xf59b810, ctx_=0x7ffff61f7c30, state=0x7fffffffd1c8) at Python/ast_opt.c:488 488 { (gdb) $gdb '/home/xxm/Downloads/cpython-364d0d20f924071b749e5a889eca22628f4892a3/python' (gdb) run Python 3.10.0a3+ (default, Apr 6 2021, 11:24:27) [GCC 7.5.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> compile("1+2" * 1000000, "-", "exec") Traceback (most recent call last): File "<stdin>", line 1, in <module> RecursionError: maximum recursion depth exceeded during compilation >>> import pdb >>> pdb.run("1+2"*1000000) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/xxm/Downloads/cpython-364d0d20f924071b749e5a889eca22628f4892a3/Lib/pdb.py", line 1597, in run Pdb().run(statement, globals, locals) File "/home/xxm/Downloads/cpython-364d0d20f924071b749e5a889eca22628f4892a3/Lib/bdb.py", line 577, in run cmd = compile(cmd, "<string>", "exec") RecursionError: maximum recursion depth exceeded during compilation ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43664> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
