The bug was found on Linux (Ubuntu) 64bit architecture and the source code was downloaded from https://www.sqlite.org/download.html. The executable https://www.sqlite.org/2015/sqlite-amalgamation-3080803.zip was downloaded and compiled from the host.
I also checked and the bug doesn't reproduce on Windows.
