It is read in line 6075 cause "interlace_framebuffer" is 1 with bitmap_line = BITMAP_ADDR16(bitmap, 2*y, 0); "y" is 256 and bitmap looks like this
- bitmap 0x0c009768 bitmap_t *
- _bitmap_base {alloc=0x07c70040 base=0x07c70040 rowpixels=912 ...} _bitmap_base
alloc 0x07c70040 void *
base 0x07c70040 void *
rowpixels 912 int
width 912 int
height 488 int
format BITMAP_FORMAT_RGB15 _bitmap_format
bpp 16 int
+ palette 0x07ee08f0 {refcount=5 numcolors=6144 numgroups=1 ...} _palette_t *
+ cliprect {min_x=0 max_x=911 min_y=0 ...} _rectangle
Maybe the issue is, that it tries to access 5line 12, but it only has a height of 488? |
