I can not find any error in your patch.
Did you kept any core/backtrace of this crash?
Maybe it is a different bug.

Hi all,

This patch fixes the last leak I mentioned. It happens when the cache of 
sslcrtvalidator_program is disabled via ttl=0.

Hi William,

     I am attaching a patch for squid-3.5 in the case you want to test it.

Hi Christos,

Great news! I can also test your patch. About the other (Notes) leaks, they 
still occur, although they are smaller if compared to the Cert Validation.

Hi William,

      We had already recognise the reason of this leek and we are testing
localy a patch.

I am not able to reproduce Notes related memory leaks.
Are the other Notes related memory leaks disappeared for you using the
r13974?

If Christos is right, you should be using r13974.


Unfortunately the patch-r13967 is fixing some similar problems. This is
the last with similar fixes.

The latest squid-3.5.13 release should include fixes for these leaks.
Which squid version are you using?
