IMO, linker script should have been changed,
from:
.data : AT (ADDR (.text) + SIZEOF (.text))
{
PROVIDE (__data_start = .) ;
*(.data)
*(.data*)
*(.rodata) /* We need to include .rodata here if gcc is used */
*(.rodata*) /* with -fdata-sections. */
*(.gnu.linkonce.d*)
. = ALIGN(2);
_edata = . ;
PROVIDE (__data_end = .) ;
} > data
to:
.data :
{
PROVIDE (__data_start = .) ;
*(.data)
*(.data*)
*(.rodata) /* We need to include .rodata here if gcc is used */
*(.rodata*) /* with -fdata-sections. */
*(.gnu.linkonce.d*)
. = ALIGN(2);
_edata = . ;
PROVIDE (__data_end = .) ;
} > data AT> text
This way linker knows from which region the .data to be loaded, and finds
overflow correctly.
