Re-running against compiled app returns "Error: unknown compression type 'COMPRESS_ZLIB+50401537'"

Running the launcher with an app right after it's built works fine:

$ go build -o app
$ ./launcher app
2023/03/23 14:37:22 Shellcode Length:  46
2023/03/23 14:37:22 Overlapping Sections in Generated Elf: .debug_line

^C

But if I stop the launcher and try to run it again with the same app I get the following error:

$ ./launcher app
2023/03/23 14:37:34 Shellcode Length:  46
2023/03/23 14:37:34 Error: unknown compression type 'COMPRESS_ZLIB+50401537' in record at byte 0x48c000

The only way I've found around this was to delete the app and recompile it:

$ rm app
$ go build -o app
$ ./launcher app
2023/03/23 14:37:51 Shellcode Length:  46

2023/03/23 14:37:51 Start section header table at: 84edb0

Is there something I'm doing wrong?
