Thanks for the response. Until now I just used GDB, cause is easy on Meson. I will try with Valgrind, but I will be slow until I find a way to reproduce the problem.
Just take the desition to report this bug, because just the issue trace the fault deeply in the SQLite secuence of destruction, but any way, I will check if the issue is in related on multi-threading destruction in GDA.
