New submission from wangjiangqiang <767563...@qq.com>:
the code is trying to visit a link list in a loop, it tries to visit the next
node in line 284 "interp = interp->next" while the current node is freed in
line 296 &q
wangjiangqiang <767563...@qq.com> added the comment:
line 295 calls PyMem_Free(key),then "key" was freed again in line 317 which
causes the bug.
