[Bug 294179] Re: ALERT - canary mismatch on efree() - heap overflow detected

[Chris Weiss]

I'm not sure what you mean, can you be more specific?  
it's a bone stock ubuntu install dist-upgraded to 8.04 from a fully working 7.10.  I restored my disk image backup to re-upgrade and it's working again, so it's something that changed in the ubuntu packages between 7.10 and 8.04 since nothing else has changed on my server.

the code that triggers this is simply a call to mssql, and only on
certain queries.  I have nearly 100 calls that work and about 5 that
don't, and there is nothing especially different about the ones that
don't work.  in fact the more complex ones with large resultsets and
multiple resultsets DO work and these small single table 5 row results
fail while other similar ones do not fail.

7.10 works + 8.04 fails == regression bug in something, somewhere.
