Description: bpo-32844: subprocess: Fix a potential misredirection of a low fd to stderr. When redirecting, subprocess attempts to achieve the following state: each fd to be redirected to is less than or equal to the fd it is redirected from, which is necessary because redirection occurs in the ascending order of destination descriptors. It fails to do so in a couple of corner cases, for example, if 1 is redirected to 2 and 0 is closed in the parent. (cherry picked from commit 0e7144b) Co-authored-by: Alexey Izbyshev izbyshev@users.noreply.github.com https://bugs.python.org/issue32844
