| 16 | # Test to reproduce the crash described in PR 26693. The following DWARF was | |
| 17 | # crashing GDB while loading partial symbols: a DW_TAG_subprogram with a | |
| 18 | # DW_AT_specification (pointing to another subprogram), without a DW_AT_name | |
| 19 | # and with a template parameter (DW_TAG_template_type_parameter). More | |
| 20 | # precisely, the crash was happening when trying to compute the full name of the | |
| 21 | # subprogram. | |
