I noticed this to, it is caused by:
2000-03-14 Elena Zannoni <ezannoni@kwikemart.cygnus.com>
* gdb.base/printcmds.c: Add typedeffed arrays.
which now puts a nonzero word after ctable2 in gdb.base/printcmds.c via
ArrayInt a1 = {2,4,6,8,10,12,14,16,18,20};
Previous versions had
int int1dim[12] = {0,1,2,3,4,5,6,7,8,9,10,11};
after ctable2, putting a zero word there.
So we now have a non zero byte after ctable2 (but only on little endian
targets).
p &ctable2[15*16]
asks GDB to print an unsigned char pointer and GDB puts out the contents
of the pointer as a string as well. As the string is no longer zero
terminated, GDB appends ellipsis.
It could be fixed by appending a zero byte to ctable2 (but I have tested
this only lightly):
