A nim-ffi library is loaded into a foreign host (Go/Rust/...) that must own OS signal handling; if the Nim runtime installs its own handlers it clobbers the host's (e.g. Go's SIGSEGV -> sigpanic recovery, stack growth, goroutine preemption), turning recoverable faults into hard process crashes. The flag can only be set on the consumer's final build command, so a dependency cannot inject it -- but it CAN refuse to compile without it. Add a compile-time guard so any consumer that omits -d:noSignalHandler fails the build with an actionable message instead of crashing at runtime (the cause of a real status-go regression). Standalone Nim binaries (nim-ffi's own tests) build with -d:ffiAllowSignalHandler. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
