Hello,

I have a bash-4.2 (installed in /home/my), compiled with GCC 4.6.1
directly from the sources. With this one, the following script:

---------------------------------
#!/home/my/bash-4.2

rm -rf /tmp/xxx
mkdir -p /tmp/xxx/folder1
ln -s folder1 /tmp/xxx/folder
if [ -d /tmp/xxx/folder ]; then echo folder; else echo no folder; fi
if [ -x /tmp/xxx/folder ]; then echo execut; else echo no execut; fi
exit
---------------------------------

produces:

folder
no execut

while the regular /bin/bash (4.1.10), with the same script:

---------------------------------
#!/bin/bash

rm -rf /tmp/xxx
mkdir -p /tmp/xxx/folder1
ln -s folder1 /tmp/xxx/folder
if [ -d /tmp/xxx/folder ]; then echo folder; else echo no folder; fi
if [ -x /tmp/xxx/folder ]; then echo execut; else echo no execut; fi
exit
---------------------------------

produces (correctly):

folder
execut


Could be a bug in bash-4.2, but...
i have noticed that it occurs only under the newest snapshots.
The change occurred between the 2011-07-21 and 2011-07-29 snapshots.

My current /proc/version | tr -d '@' is:
CYGWIN_NT-5.1 version 1.7.10s(0.249/5/3) (cgf) (gcc version 4.3.4 20090804 (release) 1 (GCC) ) 20110801 00:02:52

Could someone please have a look and reproduce this?


Regards,

Denis Excoffier.
