cannot change into directories with names containing underscores

[dd]

version 4.6.1 & 4.6.2 on MacOS

When trying to change into a directory whose
name contains an underscore (e.g., "xxx_yyy"), mc prints "Warning:
Cannot change to xxx_yyy"). mc shows the contents of the directory
xxx_yyy, but the subshell remains in the parent directory (Ctrl+O
shows shell in parent dir). After that running a command from the subshell (e.g., "clear") will pop the mc panel display to the parent directory.

when running with no subshell (mc -u), mc changes directories
successfully.

I confirm this annoying bug on Linux 32bit with bash 3.2
This bug in mc is also present in Linux using zsh shell:
​http://www.zsh.org/mla/users/2009/msg00176.html

In all cases (and shells used) -u parameter of mc workarounds the bug.
This is not file/directory access rights issue - it happens on root account also.
The most visible/reproducible this bug is when accessing directory with underscore like a_b

Possible patch (I do not use it yet):

This was fixed three years ago with changeset ​http://www.midnight-commander.org/changeset/eca5afad0fb148db1c1b1b6246d0b43da6746293 "* src/subshell.c (subshell_name_quote): Use the printf' utility instead of echo' to quote the directory name."

OK. Closed as fixed.
