--- Comment #13 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I understand that this might be the reason why others have enabled zstd always
but reading the code this case should be supported.
That is LTO generated from a GCC without ZSTD support should be supported with
one compiled with it.
Plus:
/* Compression algorithm used for compression of LTO bytecode. */
enum lto_compression
{
ZLIB,
ZSTD
};
ZSTD is 1 so it has to be something corrupting the field ...
