Re^13: weird Class::DBI::AbstractSearch problem

This is still driving me crazy. That one script stopped breaking (I couldn't tell you why), and another started. It (currently) breaks consistantly when I try to run it:

$ perl ./hist2rss.pl
hist2rss.pl: Attempt to free unreferenced scalar: SV 0x87edcb4 at /hom
+e/user/lib/modules/Class/DBI.pm line 1127.

Ok, great, I say - I'll run it under the debugger, awesome. Well, not so much - I'm running it in the debugger, and just telling it to continue:

$ perl -d ./hist2rss.pl

And it just completes it's run without any error. What's the deal? Why would it NOT break under the debugger, without me doing anything?

There sometimes are bugs that don't show up when run under the debugger. These are very rare, and are a side-effect of the way the debugger instruments the code. However, what's all this unreferenced scalar junk? This is making me think you have something wrong at a deeper level, and should consider recompiling your perl and DBI/DBD modules.	[reply]

I just saw your reply, but as it turns out, you were right. I think the DBI was compiled again 5.8.0 (which is apparently bad news). Recompiled against 5.8.3, and everything just suddenly worked. Thanks for holding my hand with this! -- zigdon	[reply]
