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