I'm sending this to both perlbug and cygwin mailing lists since I'm not sure
if it's a perl or cygwin problem. Regards,

Subject: Attempt to rmdir current directory under Cygwin Perl 5.6.1 causes
perl to abort without an error
Reply-To: [EMAIL PROTECTED]
This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.33 running under perl v5.6.1.
-----------------------------------------------------------------
[Please enter your report here]
Under Cygwin version 1.3.9, perl version 'This is perl, v5.6.1 built for
cygwin-multi'
an attempt to use rmdir on the current directory causes perl to abort
without an error
message or any other indication that it failed. This was first noticed when
using the
CPAN shell while in the cpan cache directory. CPAN.pm tried to clean up the
cache
and simply aborted without notice. I traced the culprit to
File::Path::rmtree and from
there to rmdir. The following one-liner recreates the behavior:
turnbullw@TURNBULL /tmp
$ mkdir foo
turnbullw@TURNBULL /tmp
$ cd foo
/tmp/foo
turnbullw@TURNBULL /tmp/foo
$ perl -e'rmdir "/tmp/foo" or die "dead: $!"; print "ok"'
### ^^^ Notice that perl aborted silently and never got to 'print "ok"'
turnbullw@TURNBULL /tmp/foo
$ cd ..
turnbullw@TURNBULL /tmp
$ perl -e'rmdir "/tmp/foo" or die "dead: $!"; print "ok"'
ok
### ^^^ This time it worked as expected
On the same machine using ActiveState perl version 5.6.1, build 631, perl
gives a
meaningful error when attempting to rmdir the current directory:
C:\temp>mkdir foo
C:\temp>cd foo
C:\temp\foo>perl -e "rmdir 'c:\temp\foo' or die $!; print 'ok'"
Permission denied at -e line 1.
### ^^^ This version of perl told us why it didn't work
C:\temp\foo>cd ..
C:\temp>perl -e "rmdir 'c:\temp\foo' or die $!; print 'ok'"
ok
