Once an image has .ehmeta, an eh_frame_hdr version other than 1, an eh_frame_ptr encoding other than absptr or pcrel, a 64-bit record length, an eh_frame_ptr outside the image or a missing terminator now throw instead of returning the empty answer. The test queries a fixture DLL whose .ehmeta it can break, since the unwinder reads the same section. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
