--- Comment #3 from Sebastian Huber <sebastian.huber@embedded-brains.de> ---
With Binutils 2.24.51.20140322, GCC 4.9.0 20140323, and GDB 7.7.50.20140322-cvs
I still have the problem.

An objdump with --dwarf --dwarf-check gives:

sparc-rtems4.11-objdump --dwarf --dwarf-check ticker.exe >/dev/null
sparc-rtems4.11-objdump: Warning: There is an overlap [0x668 - 0x650] in
.debug_ranges section.
sparc-rtems4.11-objdump: Warning: There is an overlap [0x6c0 - 0x6a8] in
.debug_ranges section.

Is this a problem?  I am not sure how to begin to search for the problem.  Is
this more likely a Binutils, GCC or GDB problem?

On another test program with C++ I get even more warnings:

sparc-rtems4.11-objdump --dwarf --dwarf-check sptls02.exe >/dev/null
