The first addresses linker failures and runtime errors in WebAssembly builds caused by incorrect handling of the wasm\_import\_module attribute when importing symbols from multiple Wasm modules. The second fixes Cargo's target directory locking on illumos systems, which was inadvertently disabled due to an oversight in the File::lock standard library implementation. 48 13. 13 [](/posts/how-we-found-a-bug-in-go-s-arm64-compiler-igpy1eqbw "How we found a bug in Go's arm64 compiler") Article Cloudflare · 1y How we found a bug in Go's arm64 compiler Cloudflare discovered a race condition in Go's arm64 compiler that caused sporadic crashes during stack unwinding. The bug occurred when async preemption interrupted a split stack pointer adjustment in function epilogues, leaving the stack in an invalid state. Through systematic debugging involving coredumps, disassembly analysis, and reproducer creation, they traced crashes to a one-instruction race where the runtime preempted between two ADD opcodes adjusting RSP. The fix ensures stack pointer modifications happen atomically by building offsets in temporary registers first. 47 1 14. 14 [](/posts/the-linux-kernel-looks-to-bite-the-bullet-in-enabling-microsoft-c-extensions-lfdvneg0e "The Linux Kernel Looks To "Bite The Bullet" In Enabling Microsoft C Extensions") Article Phoronix · 48w The Linux Kernel Looks To "Bite The Bullet" In Enabling Microsoft C Extensions The Linux kernel is preparing to enable the -fms-extensions compiler flag in version 6.19, allowing Microsoft C extensions that permit anonymous tagged structs and unions.
