Re: Regarding loops and memory leak

Hi,

Thanks both for testing the example :-)

Out of old habit I've been running configure like this:
./configure --enable-warnings --with-defaults=debug --with-malloc=checked

I've tried without these arguments now, and the leak disappeared in the 
test_octstr example.

But the sqlbox code that runs the same kind of loop still leak memory 
without the debug params.  I guess I have some debugging left :-(
