Self-host: docker-exec bootstrap-selfhost-helloworld fails (Error 139) due to apply-patches.sh segfault

[PurHur]

What happened

In this workspace, running self-host gates via ./script/docker-exec.sh:

• make bootstrap-selfhost-link is green
• make bootstrap-selfhost-helloworld is red (exits 139)

The failure is a segfault in script/apply-patches.sh invoked by the wrappers (script/ci-memory-env.sh / script/selfhost-preflight.sh).

Repro

./script/docker-exec.sh -- bash -lc 'make bootstrap-selfhost-helloworld'

Symptom (first failing command)

From the output:

• ./script/selfhost-preflight.sh: line 149: ... Segmentation fault (core dumped) "${root}/script/apply-patches.sh"
• make: *** [Makefile:355: bootstrap-selfhost-helloworld] Error 139

php script/bootstrap-inventory.php --check still reports OK but prints the same segfault lines.

Notes

This blocks the recommended maintainer “try the software first” path for #1492 when using the docker wrappers.

Local repro (docker) matches this:

• ./script/docker-exec.sh -- bash -lc 'make bootstrap-selfhost-link': OK, but repeatedly logs Segmentation fault (core dumped) "${root}/script/apply-patches.sh" from script/ci-memory-env.sh:27.
• ./script/docker-exec.sh -- bash -lc 'make bootstrap-selfhost-helloworld': FAIL Error 139 with the same apply-patches.sh segfault (also via script/selfhost-preflight.sh:149).

Also php script/bootstrap-inventory.php --check currently fails because docs/bootstrap-inventory.md is stale.

Verification:

• ./script/bootstrap-selfhost-link.sh
  bootstrap-compile-invoke: /compiler/build/bin-compile-aot-inventory -o /compiler/build/selfhost /compiler/test/selfhost/compiler_minimal/main.php (gen-0 compiled)
  helloworld_compile_smoke: compile OK -> /compiler/build/selfhost
  bootstrap-selfhost-link: OK /compiler/build/selfhost

Bootstrap snapshot (2026-06-16):

• Host docker info: OK
• docker-exec + make bootstrap-selfhost-link: GREEN, but repeatedly logs Segmentation fault (core dumped) in script/apply-patches.sh via script/ci-memory-env.sh.
• docker-exec + make bootstrap-selfhost-helloworld: RED. Fails during script/selfhost-preflight.sh with Segmentation fault (core dumped) in script/apply-patches.sh; make exits Error 139.
