From d1b883b52a99427d234c20e4a92ddfa6a1da8880 Mon Sep 17 00:00:00 2001 From: Eric Snow Date: Tue, 21 Mar 2023 12:47:55 -0600 Subject: gh-98608: Fix Failure-handling in new_interpreter() (gh-102658) The error-handling code in new_interpreter() has been broken for a while. We hadn't noticed because those code mostly doesn't fail. (I noticed while working on gh-101660.) The problem is that we try to clear/delete the newly-created thread/interpreter using itself, which just failed. The solution is to switch back to the calling thread state first. https://github.com/python/cpython/issues/98608 --- Python/pylifecycle.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Python/pylifecycle.c') diff --git a/Python/pylifecycle.c b/Python/pylifecycle.c index 0d546d52087..d0e85519d23 100644 --- a/Python/pylifecycle.c +++ b/Python/pylifecycle.c @@ -2062,10 +2062,10 @@ error: /* Oops, it didn't work.
