--- Comment #1 from weimin.pan at oracle dot com ---
Looks like a compiler problem which didn't emit a DW_TAG_typedef tag
for "uchar" for the template type parameter:

 <1><2d>: Abbrev Number: 2 (DW_TAG_base_type)
    <2e>   DW_AT_byte_size   : 1
    <2f>   DW_AT_encoding    : 8        (unsigned char)
    <30>   DW_AT_name        : (indirect string, offset: 0x0): unsigned char
 ...
 <2><4c>: Abbrev Number: 5 (DW_TAG_template_type_param)
    <4d>   DW_AT_name        : T
    <4f>   DW_AT_type        : <0x2d>

Instead it should generate something like:

 <1><2d>: Abbrev Number: 2 (DW_TAG_typedef)
    <2e>   DW_AT_name        : (indirect string, offset: 0x0): uchar
    <34>   DW_AT_type        : <0x38>
 ...
 <1><38>: Abbrev Number: 3 (DW_TAG_base_type)
    <39>   DW_AT_byte_size   : 1
    <3a>   DW_AT_encoding    : 8        (unsigned char)
    <3b>   DW_AT_name        : (indirect string, offset: 0x31): unsigned char
 ...
 <2><4c>: Abbrev Number: 5 (DW_TAG_template_type_param)
    <4d>   DW_AT_name        : T
    <4f>   DW_AT_type        : <0x2d>
