Sure, how about the test below?  Without the fix, I get the fail

FAIL: gdb.base/until-range-step.exp: until 2 (GDB internal error)

on x86-linux and arm-none-eabi.  With the fix applied, the fail goes
away.  I am not sure the test case name is good or clear enough.
Maybe we can rename it to pr17206.exp or something else.
