--- Comment #4 from Martin Li=C5=A1ka <marxin at gcc dot gnu.org> ---
Then we end up with 2 copies of the compressed stream:

$ cat good.txt

y.o:     file format elf64-x86-64

Contents of section .gnu.lto_.jmpfuncs.c09bc76fb7147437:
 0000 28b52ffd 20116d00 00380500 01000000  (./. .m..8......
 0010 0001001b c002                        ......

$ cat bad.txt

y.o:     file format elf64-x86-64

Contents of section .gnu.lto_.jmpfuncs.9e830355985c8f8c:
 0000 28b52ffd 20116d00 00380500 01000000  (./. .m..8......
 0010 0001001b c00228b5 2ffd2011 6d000038  ......(./. .m..8
 0020 05000100 00000001 001bc002           ............=20=20=20=20

Then we tell zstd section size and decompression fails as zstd frame header
contains a smaller size.=
