<pre>In the example shown below, the following error is reported:
ld.lld: error: section .data3 load address range overlaps with .data
<span class="quote">>>> .data3 range is [0x8000005, 0x800000C]
>>> .data range is [0x8000008, 0x800000B]</span >
linkerscript:
```
MEMORY
{
CODE (rx) : ORIGIN = 0x08000000, LENGTH = 512K
DATA (rw) : ORIGIN = 0x20000400, LENGTH = 95K
}
SECTIONS
{
.text :
{
*(.text)
} > CODE
.data : ALIGN(8)
{
. += 4;
} > DATA AT> CODE
/* This section is needed to get a new program header created for .data3 */
.data2 :

```

Looking at the ELF that we get when using `--no-check-sections`, we find the
following program headers:
```
Program Headers:
Type Offset VirtAddr PhysAddr
FileSiz MemSiz Flags Align
LOAD 0x0000000000001000 0x0000000008000000 0x0000000008000000

```
, indicating that .data3 is not aware of the alignment requirement of .data</pre>
