A recent discussion on memory-safe context switching explores the inherent safety risks and stack corruption vulnerabilities of using setjmp and longjmp in C. To overcome the language's rigid pointer model and enable safe stack relocation, developers propose workarounds like copying stack frames or strictly restoring continuations to their original memory addresses. The conversation also highlights a trend toward bypassing heavy system calls like ucontext in favor of highly optimized, custom assembly-based fiber libraries for more efficient context switching.
