Hello !
I'm not sure where the problem is but this code worked without any problem
with previous sqlite3.
Here is a backtrace of a segfault using gdb (the line numbers will not match
standard sqlite3.c because I have some custom extensions):
enter mutex 0x7fffe405f570 (1213663847) with nRef=1919906927
Program received signal SIGSEGV, Segmentation fault.
