ELF statifier / Discussion / Help: Segmentation fault on 64-bit system

Sod Almighty - 2016-08-15

When I run statifier on a 32-bit executable it produces an executable that will run on a 32-bit system. However, the resultant executable segfaults when run on a 64-bit machine. Also, if I run statifier on a 64-bit version of the executable, the resulting executable segfaults when run.

Could you please provide a bit more info:
what is your 32-bit system (distribution, version, kernel version) where statified exe works
what is your 64-bit system (distribution, version, kernel version) where statified exe fails

Output of
cat /proc/self/maps

twice for each system

Well, I'm not sure what's changed, but now it doesn't work at all, even on the 32-bit system.

As I said, four days ago the process would work on the 32-bit system, but not on my 64-bit system. Now, for some reason, it won't work on either system. I don't recall changing the code in the meanwhile.

Incidentally:

# LD_ASSUME_KERNEL=2.2.5 statifier ./linux-setup ./linux-setup-static
/bin/sh: error while loading shared libraries: libc.so.6: cannot open shared object file: No such file or directory
# LD_ASSUME_KERNEL=3.2.0.4 statifier ./linux-setup ./linux-setup-static

zsh: segmentation fault  ./linux-setup-static

Sigh :(

Segmentation fault on any D-generated 64 bit executable. Minimal example attached. If you want to compile example itself you need DMD and dub (both exists in Ubuntu software repos).

  Unfortunately, statifiied program segfault on the systems with memory randomization.
  You can try to turn memory randomization off, statify your executable and then try to run it.
