# Workaround for Folly F14 bug exposed by Xcode 26:
# Folly's F14SetFallback.h uses reinterpret_cast to access the private
# internals of std::unordered_set — an unsafe hack that relies on a
# specific memory layout. Xcode 26's libc++ might have changed that layout,
# causing the debug-only assertion (FOLLY_SAFE_DCHECK at line 234)
# to fail with SIGABRT.
# Since F14SetFallback.h is a header-only template compiled by any
# target that includes it, we define NDEBUG for ALL targets to set
# folly::kIsDebug=false, disabling the assertion. This matches the
# behavior of Release/Production builds which already define NDEBUG.
