I'm current maintainer of GDA[1], I've updated embbeded version of SQLite
to 3.25.2, but I found an issue with a segfault due to a "corrupted
double-linked list".
In order to reproduce it:
a) Checkout libgda from its respository[1]
b) compile using its meson:
$ meson _build
$ cd _build
$ ninja
$ meson test Virtual --repeat 100 --gdb
Last command runs a unit tests called Virtual, it run it 100 times in a GDB
session, you may need to repeat the operation or increase number upto 200
times.
GDB will stop at segfault.
This is the latest backtrace:
corrupted double-linked list
Thread 1 "check_virtual" received signal SIGABRT, Aborted.
