[INFO] /home/pi/v4l2rtspserver/src/V4L2DeviceSource.cpp:29
Fatal glibc error: malloc assertion failure in sysmalloc: (old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)

it worked perfectly with bullseye. After the migration I did a git pull, compiled and installed again. The error is almost perfectly reproducable. In one of maybe 50 tries, the stream starts for a second and then the crash occurs with a similar error message.
