It's a widespread problem, Solaris tools get just as confused (although
nothing coredumped on me). The script, btw, can be expressed as a perl

perl -e '$a = shift; while(mkdir($a, 0755)) { chdir $a; }' <dir>

which will go as deep as your OS allows. To get rid of it, try

perl -e '$a = shift; 1 while(chdir($a));
do { chdir("..") } while(rmdir($a));' <dir>

where <dir> is the name of the directory tree you want to create/delete.
