Subject RE: [RELEASE CANDIDATE]: mod_perl-2.0.6 RC1
Date Mon, 13 Feb 2012 09:15:34 GMT
I'm afraid the details are not clear to me either, but I have tried the two patches out (after
correcting an instance of code-before-declaration which VC++ doesn't accept in C files) and
I find that (with the LimitExcept change reverted as per current svn Trunk) they make no visible
difference to my setup: I don't see the "free unreferenced scalar" errors in the log file
after running the tests with or without the patches, but I do still get an "Out of memory!"
crash mid-way through the test suite either way :-(

Looks like it made it through.  Suggest inlining your patches next time instead of using attachments,
sometimes the list code may filter on those.

I looked through the patches and grok the syntax, but the finer details aren't clear to me
yet.  Maybe some of the other devs
(gozer,steve,torsten) can comment on them.  I'll hold rc2 for a few days to give them a chance
to respond.

Can you post some of that error log which shows the error?

Thanks for the contribution.  Anyone else here see those errors previously, or can reproduce
them now?
