MC hungs for 1-2 second when open folder plus side-effects

[Bishop]

When i try enter one of folowing folders

  /Home/Incoming/Anime/Wait for Store/[2021Q3] Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta X [++]
  /Home/Incoming/Anime/Wait for Store/[2021Q4] Shin no Nakama ja Nai to Yuusha no Party wo Oidasareta node, Henkyou de Slow Life suru Koto ni Shimashita [++]

MC hungs for 1-2 seconds. After it if i try quit MC via F10 i got "The shell is still active" warning. If i switch to shell (Ctrl+O) i see clean shell. But if i press Enter i see those command

cd "printf '%b' '\0057Home\0057Incoming\0057Anime\0057Wait\0040for\0040Store\0057\01332021Q3\0135\0040Otome\0040Game\0040no\0040Hametsu\0040Flag\0040shika\0040Nai\0040Akuyaku\0040Reijou\0040ni\0040Tensei\0040shiteshimatta\0040X\0040\0133\0053\0053\0135'"

I use Oracle Solaris if this is matter. Bug also exist in 4.8.28.

Is this some kind of remote filesystem, or it's just a "normal" folder on your filesystem? What shell are you using? It seems that because of some delays the directories get desynchronised between mc and subshell.

[Bishop]

Normal folder with 12 files. If i change its name its work fine. So, i think, only reason can be in this full path (because if i move it in another place its again works fine).

I use bash.

This is weird. I did (on Ubuntu Linux)

mkdir -p "Home/Incoming/Anime/Wait for Store/[2021Q3] Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta X [++]"

and can walk without any problems. Can you make a reproducer?

[Bishop]

/etc/profile that lead to bug

[Bishop]

1) In your cmd you forgot leading "/" in path.
2) I check problem on Alpine Linux 3.17 and it is not exist.
3) If i change shell type to sh problem is gone.
4) And if i complitly disable my "profile" and "bashrc" config files - problem are gone.

OK. Looks like a problem in profile file (now, for tests, bashrc is justs moved out). So i find point:
if "/etc/profile" is empty - all works;
if "/etc/profile" have minimal text - all works, but...
i can`t undestand bug exist conditions, because file that i attach dont work (and yes, comment strings in it is source of problem too, because if i remove them - all start works).

The only one idea i have - problem connected with time that processing of "/etc/profile" takes. And timeout is realy very very small (some ms, or even us).
