What is the bug or the crash?

I wanted to create yearly binary rasters for Global Forest Change dataset

I used if ("Hansen_GFC-2024-v1.12_lossyear_70N_080E_mosaic@1" = 1, 1, 0) expression in raster calculator

However, it just failed with message "could not create destination file"

When I tried to investigate further, I noticed that the actual error appears in OpenCL console and says:

2026-01-17T12:10:33     CRITICAL    Error building OpenCL program: <kernel>:16:94: error: used type 'float' where floating point type is not allowed
              resultLine[i] = ( ( float ) ( ( float ) input_raster_0_band_1[i] == ( float ) 1 ) ) ? ( ( float ) 1 ) : ( ( float ) 0 ) ;
              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^

When I tried to run the same expression with acceleration turned off, everything worked nice

Even if it can not be fixed, probably a more user-friendly error message should be shown

Steps to reproduce the issue

1. Enable OpenCL acceleration
2. Download any Global Forest Change data (or probably any other data)
3. Try to execute something like if ("Hansen_GFC-2024-v1.12_lossyear_70N_080E_mosaic@1" = 1, 1, 0) in a raster calculator
