Hi,
This patch fixes PR123264.
The lack of TYPE_NAME being set in qualified struct types meant that
dump_generic_node got stuck in an infinite loop between
print_struct_decl and dump_function_declaration.
Regstrapped on x86_64-linux-gnu, committed to mainline, and backported
to releases/gcc-13, gcc-14, and gcc-15.
Regards,
Iain.
