A deep dive into Rust and C memory interoperability
An in-depth exploration of what happens when Rust and C memory allocators collide, featuring crash analysis.
Whether it’s the intricacies of the CPU cache hierarchy, memory alignment, or the behavior of allocators under concurrency, these low-level details can have profound impacts on system performance and correctness. Use case: Development and debugging, catching memory corruption early Pros: Detects buffer overflows, use-after-free, double-free Cons: ~20 bytes overhead per allocation, slower than standard malloc Core dumps: ulimit -c unlimited and analyzing with gdb Memory inspection: x/32gx $rsp to examine stack contents Backtrace analysis: bt full to see the exact crash location LD_PRELOAD hooks: Intercept malloc/free to trace allocations
