This article describes a debugging journey where a Rust service's memory remained high under load despite no leaks, due to glibc's ptmalloc allocator not releasing freed memory back to the OS. It explains the allocator behavior and provides insights for Rust developers.
An article investigating platform support for GNU extensions to Basic Regular Expressions (BRE), specifically the `\+` operator, and finding it works on FreeBSD, macOS, and musl-based distributions like Chimera Linux.
This article discusses the practical challenges of writing portable C code due to reliance on non-standard compiler extensions and glibc's conditional headers, illustrating with examples from building a C compiler.
This blog post explains the current double free detection mechanism in glibc malloc's per-thread tcache, identifies a flaw that allows cross-thread double frees, and proposes a potential fix using randomized keys per thread.
Casuarina Linux is an experimental Linux distribution derived from Chimera Linux, using glibc instead of musl for better binary compatibility with the GNU/Linux ecosystem. It combines an LLVM toolchain, Dinit init system, and apk package manager, currently available for x86_64.
