	tl;dr: RipGrep 15.2.0 musl binaries occasionally segfault during highly concurrent searches over very large trees (~20GiB, 1.8M files), with the crash occurring inside musl's mallocng heap integrity assertion during a calloc from opendir. The reporter reproduced it reliably on a 24-core system by looping rg over a synthetic tree, suggesting a bug in musl's mallocng allocator under heavy multithreaded allocation rather than in ripgrep itself.
	HN Discussion: ~Notes that the analysis appears AI-generated and was flagged as such in the kernel patch discussion ↑Musl's mallocng is known to perform poorly under multithreaded contention and should be replaced ↑Points to the detailed analysis document as a better reference for understanding the bug •Running ripgrep on HPC cluster filesystems is a workflow problem regardless of the bug ↓Questions the diagnosis, asking why only musl is affected and whether the kernel bug is confirmed
