Description Jerry James 2009-10-12 21:26:59 UTC 
Description of problem:
Any use of automake causes this error message to be printed on the console:

Use of uninitialized value in formline at /usr/bin/automake line 8334.

Version-Release number of selected component (if applicable):
automake-1.11-2.fc11.noarch

How reproducible:
Always

Steps to Reproduce:
1. automake --help
  
Actual results:
Near the bottom of the output, look for the line "Files which are automatically distributed, if found:", which is followed by the error message reported above.  That error message is also triggered when I run "autoreconf" on my projects.

Expected results:
No error message.

Comment 3 Stepan Kasal 2009-11-24 13:01:51 UTC 
This is not a bug in automake, it is a bug in the Perl itself.
I was able to reproduce the behavior with a short script, attached here in comment #2.
Consequently, I'm changing the Component to perl.

Then I noticed that the problem appears with recent builds of perl only.
Next, I found out it was introduced in perl-5.10.0-77, with a patch that was supposed to work around another bug: in perl taint mechanism.
As it shows that the patch can have unexpected consequences, I'm backing it out.

Consequently, this bug is resolved in perl-5.10.0-85.

The unfortunate patch is now saved as an attachment to bug #510127.
