First, well done for identifying your workaround. I use Xcode and iOS and I've had situations where compiling without optimization cures crashes. But they haven't involved SQLite code. I don't know how much optimization improves sqlite's speed. Might help a lot, might not. One problem with sqlite is that it has to compile on a lot of platforms with a lot of compilers and it's impossible to get rid of all warnings under those conditions. If possible play with each of the optimization levels and find out which level is causing the problems. If you can figure out what part of the C code is causing the problem, or post an extract from the crash log which gives symbol names, someone here might be able to figure out what to fix in the code.
