Hi everybody,
While testing some database upgrade function of mine, I ran into a
segmentation fault. I started looking at the possible cause in my
code, but I soon realized the crash would only happen using SQLite
3.7.7 or 3.7.8. If I use 3.7.6 or lower, things go safely.
Since I am not familiar with SQLite's internals, I have run the thing
under Valgrind and GDB to get some backtraces. Here is Valgrind's
report:
And here is the GDB backtrace (using 3.7.8):
