But you did know. You said:

The version of rm you are using is 4.0.36 from the GNU fileutils
package. And that happens to be later than 4.0s (equivalent to 4.0.19
in the new numbering) that the fix was reported fixed in. It is
possible that a glibc problem is occurring on your system.

An excellent case example! Thank you very much for including it.
When I try it on linux-2.2.18 with glibc-2.1.92 I get the following
while creating the directories.
cd: could not get current directory: getcwd: cannot access parent
directories: Numerical result out of range
find . -print | tail -n 1 | wc -c
4202
On hpux 10.20 I also get something similar but at a different length.
And the message does seem more appropriate and correct.
cd: could not get current directory: getcwd: cannot access parent
directories: File name too long
find . -print | tail -n 1 | wc -c
1038
I believe I am running into the filesystem max path length in both
cases. It just can't make a path any deeper at that point.
But using rm version 4.1 I cannot create any failures removing that
deep path on either system.
