You're casting, but the value does not fit in 32 bit and the warning still remains. I am afraid that 32 bit for gd->ram_size are not enough anymore... We can fix the warning setting maybe a lower amout of memory (I am expecting that now the value is truncated and a wrong output is shown on the console), but for the future gd->ram_size should move to 64 bit. Best regards, Stefano
