What causes the 'BFD: Dwart Error:' ?

[PRC]

  1.c
-----------------------------------------
#if 1
static char mydata1[0x2000] __attribute__(( section(".1.c") ));
#endif

int half(int x)
{
	return x/2;
}


  3.c
-----------------------------------------
static char mydata3[0x2000] __attribute__(( section(".3.c") ));


  link.xn
-----------------------------------------
OUTPUT_ARCH(mips) 
ENTRY(main)

SECTIONS

	.text 0x80051000 :
	{
	 *(.text)
	 *(.rodata*)
	}
 	 
	.data :

	 *(.data)
	 *(.sdata)

build
-----------------------------------------

BFD: Dwarf Error: found dwarf version '0', this reader only handles version 2 information.


If I comment out definition of `mydata1' in 1.c, the objdump error disappear as well.
How does this error occur?
