[rt-users] Scalar::Util::Weak Problem (Fixed!)

[jkaufman at footlocker.com]

It's possible. How does one go about disabling weak references? I was 
unable to get it to compile using 5.8.7 (self compiled), 5.8.0 (Shipped 
with AIX), 5.8.5 (Compiled on a previous release of Aix v5.2), and 5.8.7 
(PDSLIB compile). Nothing worked until I tried 5.8.8 (self compiled).  I 
can't say I have any idea WHY 5.8.8 worked, but it worked on 
Scalar::Util::Weak...  Sub::Uplevel is now the problem child :)

A whole bunch of:

Use of uninitialized value in string eq at 
/home/root/.cpan/build/Sub-Uplevel-0.09/blib/lib/Sub/Uplevel.pm line 123.

It will install, but anything that uses it sometimes will fail their make 
test...sigh...  Hopefully this will not be a future problem...

I suspect you may have actually been bitten by the same bug that bit me a
couple of months ago. Some precompiled versions of Perl (notably the one 
that
ships with RHEL 4.0's "up2date" utility) have weak references disabled at
compile time. RHEL 4 ships with weak refs enabled in the distributed 
version,
but a later "security update" from "up2date" turns it off -- and this is 
not
documented. My server got updated from Perl 5.8.5 build (something) to 
Perl
5.8.5 build (something slightly later) that way, and it utterly broke RT.
I ripped out what little hair I have trying to find that one -- you don't
instinctively look for version compatibility issues when the version 
didn't
change.

I'm glad you got it working, whatever the underlying cause.
