# jemalloc 5.3.1 source compat patch: libstdc++ 16+ removed
# std::__throw_bad_alloc from the public ABI, breaking
# src/jemalloc_cpp.cpp on GCC 16 / libstdc++ 16 toolchains (notably
# Chainguard go-fips:v1.26.3.1-dev and later). The sed substitution
# below is a no-op on older libstdc++ (exact-match) and rewrites the
# legacy call to the standard `throw std::bad_alloc()` idiom on
# libstdc++ 16+. Drop the sed line once a tagged jemalloc release
# upstreams the fix and JEMALLOC_URL bumps past it.
