Describe the bug The caddy server built with go fails to start due to the following error:

[    0.171790] CRIT: [appelfloader] <brk.c @   27> Cannot handle multiple user space heaps: Not implemented!
[    0.176019] CRIT: [appelfloader] <brk.c @   44> Failed to increase heap: Not implemented!
fatal error: failed to reserve page summary memory

To Reproduce Steps to reproduce the behavior:

  1. Set up the correct directory structure (clone the repositories, see snippet below)
  2. Build the caddy server static PIE executable
  3. Run it with ./run_elfloader ../static-pie-apps/caddy/caddy-2.6.2/cmd/caddy/caddy
  4. See error

Expected behavior I expect it to run without errors.
