[Bug debug/41736] missing DW_TAG_template_*_ in some cases
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41736 --- Comment #10 from Tom Tromey tromey at gcc dot gnu.org --- Today I noticed another case. If you have a template like: templatetypename R, const char *NAME, typename A [...] ... then NAME is not given a value in the instantiation: 265c5: Abbrev Number: 51 (DW_TAG_template_type_param) 65c6 DW_AT_name: R 65c8 DW_AT_type: 0x3042 265cc: Abbrev Number: 122 (DW_TAG_template_value_param) 65cd DW_AT_name: (indirect string, offset: 0x6768): NAME 65d1 DW_AT_type: 0x66ac 265d5: Abbrev Number: 51 (DW_TAG_template_type_param) 65d6 DW_AT_name: A1 65d9 DW_AT_type: 0x30aa

(In reply to comment #3)
The ordinary cases work fine with svn trunk gcc.
However, member pointers still don't have all the info emitted.
Consider this test case:
struct S { int f; };
templateint S::*MP struct T { };
TS::f v;
For v's type, I just see:
24f: Abbrev Number: 6 (DW_TAG_template_value_param)
50 DW_AT_name: MP
53 DW_AT_type: 0x58
That is, this parameter has no value.
I have opened PR debug/46955 to track this as I believe the bug you describe is
slightly different from this one, even if they fall in the same category.

I have opened PR debug/46973 to analyse and track this issue there.
