system reboot with Qt 4.8.7 and '-system-sqlite' using libsqlite >= 3.21.0
I'll try to describe the issue very brief and will add further info, if needed/requested.
Qt 4.8.7 (upgrade is not an option)
built with gcc-7.3.1 for an imx25 board
linux kernel 4.17.19
the need to use "attach" and "detach" inside transactions and therefor using "-
system-sqlite" with a newer version of libsqlite (greater than 3.21.0 released on 2017-10-
Description / observed behavior
The code that uses "attach" and "detach" inside transactions runs every 15min (copies data
from in-memory sqlite files to sqlite files on persistent storage). This is never reached,
since the system is restarted via watchdog every (roundabout) 10 minutes. In this time
the system collection various data from various I/O.
Qt with built in sqlite (184.108.40.206) -> system works as expected
Qt with '-system-sqlite' and libsqlite 220.127.116.11 -> system works as expected
Qt with '-system-sqlite' and libsqlite 3.21.0 -> system slows down till reboot via
Qt with '-system-sqlite' and libsqlite 3.24.0 -> system slows down till reboot via
Are there any known incompatibilites between Qt and libsqlite versions?
Or maybe compilte time flags that could should be added?
