We've moved to GRUB 2 as a development platform. Please can you check if this bug still applies there, and if it does, reopen it?

Thanks

Hi,

in char_io.c the memcheck function uses "int addr" to store addresses and does bounds checking on it. On systems with over 2G of ram the "int addr" will be negative and the bounds checking will fail producing an "ERR_WONT_FIT".

The attached patch changes the addr and len argument to unsigned long long as well as the two helper functions.
