In Syslinux-5.00, is the goal that the core and .c32 modules alike will use the same heap? There is a bug I am thinking about: - QEmu with 1024 MiB RAM - Syslinux 4.06 - .c32 can realloc() up to 1013 MiB - QEmu with 1024 MiB RAM - Syslinux 5.00-pre9 - .c32 can realloc() up to 45 MiB I am wondering if there's a maximum-allocation-size being hit, or if it's actually a bug I should look
