No, please _do_ show us the _exact_ full directory name that caused
this to happen.  You can do that safely, without fearing any loss of
data, if you run "rm -ir" instead of just "rm -r" or, worse' "rm
-rf".  It's also advisable to begin with removing a single file (thus
not risking to lose any data except that file, which can be a trash
file).  Or are you saying that the problem only happens with "rm -r"?

It is impossible to debug this without seeing at least one full
example.

This name is much longer than 67 characters, even though you replaced
part of the name with 1234567890.

Also, where do you see that ``directories from the root dir are
scanned''?  ".libc/libstdc++.lax/..." does not start from the root.

Finally, what is the command invoked by the Makefile (or a shell
script) which runs `rm' in this case?
