dhatbj/SignalRecovery
A C library that keep your program from crashing when illegal access occurs.
A C library that catches POSIX signals (SIGSEGV, SIGFPE, etc.) using sigsetjmp/siglongjmp to give you a try/catch-style escape hatch from crashes. Aimed at iOS/macOS/Linux developers who need to survive crashes in third-party code or buy time before a proper fix. The README is admirably honest about why you probably shouldn't use it.
The sigsetjmp/siglongjmp approach is the correct mechanism for this — no magic, just the POSIX primitives done right. Thread safety and nested try/catch support are handled, which are the two obvious failure modes for a naive implementation. The README explicitly warns against using this as a long-term fix, which shows the author understands the tradeoffs. Single-file implementation means integration is trivial.
Abandoned since 2019 — no updates in seven years, which matters for a library touching signal handling on platforms that keep changing. No Windows support, so if your crash happens on a platform not listed, you're writing the port yourself. Stack unwinding skips destructors and cleanup code, meaning memory and resource leaks are essentially guaranteed in any non-trivial catch block — the README mentions this but it deserves more emphasis. 54 stars and no CI means you're adopting untested code for one of the most dangerous patterns in systems programming.
