This looks like latent bug in dwarf2out. There is location list:
.LLST2:
.long .LVL0-.Ltext0 # Location list begin address (*.LLST2)
.long .LVL1-.Ltext0 # Location list end address (*.LLST2)
.value 0x2 # Location expression size
.byte 0x91 # DW_OP_fbreg
.sleb128 0
.long .LVL1-.Ltext0 # Location list begin address (*.LLST2)
.long .LFE6-.Ltext0 # Location list end address (*.LLST2)
.value 0x2 # Location expression size
.byte 0x75 # DW_OP_breg5
.sleb128 8
.long 0x0 # Location list terminator begin (*.LLST2)
.long 0x0 # Location list terminator end (*.LLST2)
and LFE6 is not defined. It is used from from foo as:
.uleb128 0xb # (DIE (0x297) DW_TAG_lexical_block)
.uleb128 0x10 # (DIE (0x298) DW_TAG_formal_parameter)
.long 0x20d # DW_AT_abstract_origin
.long .LLST2 # DW_AT_location
.uleb128 0x10 # (DIE (0x20d) DW_TAG_formal_parameter)
.long 0xd5 # DW_AT_abstract_origin
.long .LLST1 # DW_AT_location
.uleb128 0x8 # (DIE (0xd5) DW_TAG_formal_parameter)
.ascii "t\0" # DW_AT_name
.byte 0x1 # DW_AT_decl_file (b.c)
.byte 0x22 # DW_AT_decl_line
.long 0x78 # DW_AT_type
