Hi,
I am using version 3.6.18 of sqlite and see the below data race (as shown
by valgrind/Helgrind tool). Was wondering if this has been captured anywhere
or a fix for it is available in the latest version 3.7 ( I was sort of
considering an upgrade, if it included a fix for this). Any info on this or
pointers in the right direction would be appreciated much.
