Failed to allocate memory for resized reference image\n

Error message

Failed to allocate memory for resized reference image\n

What it means

Allocation for the resized reference image buffer failed. Guard: validate image dimensions are within sane bounds before allocating; on failure abort with an out-of-memory error instead of dereferencing null.

Solutions

Free memory or reduce reference image dimensions so the resize allocation succeeds.
Check overall memory usage of the backend process.
