Raspberry Pi 5 crash in 1.5.2 due to jemalloc / 16KB page size incompatibility

[holas1337]

Description

Pagefind crashes on Raspberry Pi 5 starting from version 1.5.2.

The last working version is:

• 1.5.0 → works
• 1.5.2 → crashes

The failure is caused by jemalloc failing on systems with 16KB memory
page size (Raspberry Pi OS ARM64 default).

---

Environment

• Device: Raspberry Pi 5 (ARM64)
• OS: Raspberry Pi OS (Linux)
• Page size: 16KB
• Node: npx / npm

---

Versions tested

Version Result

---

1.5.0 works
1.5.2 crashes

---

Steps to reproduce

npx pagefind@1.5.2 --site public/static --output-path public/pagefind

---

Error output

<jemalloc>: Unsupported system page size
memory allocation of 16 bytes failed

---

Expected behavior

Pagefind should run on ARM64 Linux systems regardless of memory page
size configuration (including Raspberry Pi 5 with 16KB pages).

---

Actual behavior

Binary crashes immediately due to jemalloc initialization failure on
16KB page size systems.

---

Suspected cause

• jemalloc introduced or enabled in builds starting around 1.5.1
• Raspberry Pi 5 ARM64 uses 16KB page size, incompatible with this
  configuration
• 1.5.0 likely uses system allocator or different build flags

---

Impact

• Raspberry Pi 5
• ARM64 systems with 16KB page size
• Other non-standard Linux memory configurations

---

Workaround

npx pagefind@1.5.0

Or run indexing on CI / local machine and deploy static output.

---

Request

• Provide ARM64 builds without jemalloc
• Allow fallback to system allocator
• Detect 16KB page size systems
• Provide Raspberry Pi compatible build

Interesting! I'll look at something for this. I don't think I have a Pi 5 nearby, but I have some Pi 4s sitting around so I can see if I could reproduce it. On >=1.5 the linux musl performance is rather bad on the default allocator, so most likely our best solution is to blanket set LG_PAGE=16 for the arm musl builds.
