I guess the cause is in your compiler, because the compression code has not
changed between 1.24 and 1.25. Turns out that was compiled with Clang.
Confusion come from the fact that when I checked strings for GCC and got
exactly the same as with v1.25-rc1 ~~~ $ strings prog | grep GCC: ~~~ But
when dug a bit the net I found this tool: ~~~ $ objdump -s --section .comment
prog ~~~ that shown clang along with GCC, therefore I had to conclude it was
compiled with Clang. Sorry for false alarm. -- Plzip faster compression
and slower decompression is still a thing. ~~~ $ time lzip-1.25-rc1 -kf
