I use Binutils I encountered an error in the G++ 4.8 testsuite on ARM:

/opt/rtems-4.11/bin/arm-rtems4.11-ld: region `UNEXPECTED_SECTIONS' overflowed by 2053 bytes
collect2: error: ld returned 1 exit status

This is because my linker command file contains

  .unexpected_sections : { *(*) } > UNEXPECTED_SECTIONS

to catch all unexpected sections.

The unexpected section is this:

objdump -h debug4.o
 10 .debug_macro  00000804  00000000  00000000  0000019d  2**0

The standard linker command file has no hint. A "arm-rtems4.11-ld --verbose | grep debug_macro" yields nothing.

I added this line to my linker command file:

.debug_macro 0 : { *(.debug_macro) }

Is this the right fix? If it is ok, then why doesn't the standard linker command file have it?
