I see the same issue as far back as 4.1.2.
As I mentioned, it works in 3.3.3. I compared readelf outputs. The difference
is that in 3.3.3 the typedef points to a DW_TAG_base_type entry, which supplies
the size of 1 -- but also makes the type look like "unsigned char" instead of
enum. That at least doesn't break the debugger but it isn't ideal either.
<1><6d>: Abbrev Number: 6 (DW_TAG_variable)
<6e> DW_AT_name : foo
<72> DW_AT_decl_file : 1
<73> DW_AT_decl_line : 4
<74> DW_AT_type : <0x3a>
<78> DW_AT_external : 1
<79> DW_AT_location : 5 byte block: 3 1 0 0 0 (DW_OP_addr: 1)
<1><3a>: Abbrev Number: 4 (DW_TAG_typedef)
<3b> DW_AT_name : e1
<3e> DW_AT_decl_file : 1
<3f> DW_AT_decl_line : 1
<40> DW_AT_type : <0x44>
<1><44>: Abbrev Number: 5 (DW_TAG_base_type)
<45> DW_AT_name : (indirect string, offset: 0x0): unsigned char
<49> DW_AT_byte_size : 1
<4a> DW_AT_encoding : 8 (unsigned char)
