That is not true.
DW_OP_stack_value terminates DWARF Single Location Description.
But DW_OP_bit_piece is not an operation that appears in the single location
description,
it is a DWARF Composite Location Description.
.byte 0xc # DW_OP_const4u
.long 0x52b7a
.byte 0x9f # DW_OP_stack_value
.byte 0x9d # DW_OP_bit_piece
.uleb128 0x19
.uleb128 0
.byte 0x9d # DW_OP_bit_piece
.uleb128 0x7
.uleb128 0
.byte 0xa # DW_OP_const2u
.value 0x1278
.byte 0x9f # DW_OP_stack_value
.byte 0x93 # DW_OP_piece
.uleb128 0x4
I see myself means that 25 bits have value 0x52ba7 (S0::a), then 7 bits are
padding bits and then 4 bytes have value 0x1278.
If LLDB doesn't handle that, it is broken.
