tips: solve error `Segmentation fault (core dumped)`

[IceCodeNew]

A probable cause for the Segmentation fault (core dumped) error is that the UPX-compressed binary failed to self-unpacked and run on the current OS. This case has been caught on the Rocky Linux 9.1 OS. (However, I can not reproduce this problem inside the docker image rockylinux:9.1)

People who ran into the same condition may try downloading the binary of UPX on the GitHub releases page, then issue the command upx -d ./gg to revert the compression.

Here is an example:

[root@xxx git]# ./test-bin
Segmentation fault (core dumped)
[root@xxx git]# upx -d ./test-bin

Thank you, I am also using Rocky. Congratulations on successfully running gg. sudo dnf install upx sudo upx -d $(which gg)
