State-Changed-Why:
    There could be any number of problems here.
    
    The command line/console window use different mechanisms to do the disassembly: the Source Window reads instructions from the executable file, while the console will read from the target. What happens if you do:
    
    $ powerpc-eabi-gdb -nw -nx -q foo.elf
    (gdb) disassemble DeleteChar
    
    Does it also show ".long 0x0"? If not, I'll need a testcase from you.

>Description:
When debugging target over a serial line, ASSEMBLY, MIXED, and SRC+ASM source window modes do not display the correct assembler instructions of the source files. 

In the source window:

-	0x108c810	<DeleteChar+228>:	.long 0x0
-	0x108c814	<DeleteChar+232>:	.long 0x0
-	0x108c818	<DeleteChar+236>:	.long 0x0
-	0x108c81c	<DeleteChar+240>:	.long 0x0
-	0x108c820	<DeleteChar+244>:	.long 0x0
-	0x108c824	<DeleteChar+248>:	.long 0x0
-	0x108c828	<DeleteChar+252>:	.long 0x0

Using "disassemble" command on the console:

0x108c810 <DeleteChar+228>:	sth	r12,54(r30)
0x108c814 <DeleteChar+232>:	rlwinm	r12,r12,16,16,31
0x108c818 <DeleteChar+236>:	sth	r12,52(r30)
0x108c81c <DeleteChar+240>:	lwz	r11,12(r1)
0x108c820 <DeleteChar+244>:	mr	r12,r11
0x108c824 <DeleteChar+248>:	addi	r11,r11,1
0x108c828 <DeleteChar+252>:	stw	r11,12(r1)
