Thank you for the info. I had a look at staticx - as far as I understand it unpack all shared libraries into temp location and run from it.Statifier uses kind of snapshot when all libraries already loaded, hence the different.

Looks like that for some reason /usr/lib/statifier/elf_class ./auCDTect failed with status 136. It's mean that program was killed by the signal SIGFPE. Strange.

Please check if you /usr/include/sys/ptrace.h defines enum __ptrace_request If not try to find file with this enum Valery On Wednesday, November 6, 2019, 11:26:09 AM GMT+2, vania vania99@users.sourceforge.net wrote: alpine:~# gcc -v Using built-in specs.

Hi. Could you please tell me what gcc version you have?

Could you please send me output of the readelf -aW <your_original_exe></your_original_exe>

I was right after all. In the kernel in the file fs/binfmt_elf.c /* Sanity check the number of program headers... */ if (elf_ex->e_phnum < 1 || elf_ex->e_phnum > 65536U / sizeof(struct elf_phdr)) goto out; /* ...and their total size. */ size = sizeof(struct elf_phdr) * elf_ex->e_phnum; if (size > ELF_MIN_ALIGN) goto out; First check limit phdrs size to 64K, but second one - to the ELF_MIN_ALIGN. On the x86_64 system ELF_MIN_ALIGN is 4096. When I run your executable "as is" I get following bash: ./nix-instantiate-static:...

Ooops. I was wrong. Kernel able to run elf with total size of phdrs up to 64K. So problem is not the number of phdrs
