Description Andrey 2002-11-20 14:44:41 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461)

Description of problem:
I tried to match the pattern and the then split up found subpattern by 'split' 
function with pattern as a delimiter.
Function 'split' affects value of variable '$1'. This doesn't take the place on 
Red Hat 7.3 and Windows.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. execute

Actual Results:  MakefileData.result.dat contains '0085\000uilder.h', where 
\000 after 0085 is zero byte

Expected Results:  MakefileData.result.dat should contain 'artsbuilder.h'

Additional info:

if copy value of $1 to another variable after doing pattern match and use that 
varible in 'split' function instead of $1 then all will be correct.
if ($MakefileData =~ m/\nlibartsbuilder_la_COMPILE_FIRST\s*=\s*(.*)\n/) {
    my @compilefirst = split(/[\s\034]+/, $1); 	# @compilefirst should 
contain 'artsbuilder.h'
    print "compilefirst=@compilefirst\n";	# but contain 0085\000uilder.h, 
where \000 after 0085 is zero byte

Can someone test the script & data provided in this report and verify if this is
still an issue?

Comment 4 Ville Skyttä 2005-05-28 15:32:56 UTC
perl-5.8.5-12.FC3 and perl-5.8.6-15 produce the expected results.
