If you're going to control it via an environment variable, why not just make a LD_PRELOADed shared library which intercepts memcpy() in the usual manner? Doing it that way has the added benefit that anybody could use it immediately, without needing to replace their glibc with a patched version that will never get merged upstream. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
