 Replying to [comment:39 dbl001]:
 > Why are '___register_frame_table' and '___register_frame_info_bases'
 missing with '-reexported_symbols_list' on x86 Macs but not on M Macs?
 What library is missing or incomplete?

 These symbols, `__{,de}register_frame_{info,table}*`, have indeed been
 removed from the macOS 15 SDK for both architectures.

 The GCC build for mac-x86_64 builds libgcc_s.1, but mac-arm64 does not.
