Description Flags
Initialise structures to zero to avoid potential problem with numeric comparison none

Description Stephen Quinney 2018-12-20 15:22:14 UTC 
Created attachment 1515903 [details]
Initialise structures to zero to avoid potential problem with numeric comparison

Description of problem:

We use the Parse::DMIDecode perl module on all our EL7 machines as part of our inventory system. Mostly it works fine but on a small number of machines it fails with this error about an uninitialized value:

perl -MParse::DMIDecode -wE 'my $decoder = new Parse::DMIDecode; $decoder->probe'
Use of uninitialized value $data{"structures"} in numeric lt (<) at /usr/share/perl5/vendor_perl/Parse/DMIDecode.pm line 160.

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

0.03-5

How reproducible:

About 1% of our machines, I've not checked but probably all similar hardware.

Additional info:

This seems to be similar to a bug reported in CPAN many years ago:

https://rt.cpan.org/Public/Bug/Display.html?id=54956

except that the supplied patch in that report does NOT work. I have attached a patch which fixes the problem when applied to the 0.03-5 SRPM.

Regards,

Stephen Quinney

Could you provide "dmidecode" command output from the machine where you observe the warning?
