    initial v1  
    1 The size of the picture after decompression is `22000 * 17000 * 4` which is more than 1.4 GB. On x86 process heap starts at 384 MB what makes less than 200 MB of virtual address space available for all other data that process may need (including temporary buffers for decompression, stacks, loaded elf images, etc).
     1The size of the picture after decompression is `22000 * 17000 * 4` which is more than 1.4 GB. On x86 process heap starts at 384 MB. Lower addresses are partially occupied by elf images and addresses near the top of address space available for process are occupied by stacks. Any attempt to allocate anything big (including temporary buffers for decompression) will fail.
