This is pretty damning evidence that there is a bug of some sort in
the toolchain(or
GDB specifically).

GDB should never issue this packet regardless of what OpenOCD, Eclipse or the
application does wrong... it asks to read 4 bytes at address
0xfffffffe  which runs
off the end of the universe(address space at least).

Can you try the GDB from http://www.zylin.com/gccbinary.html ?
