It looks by "tried valgrind" you man running just plain valgrind
instead of configure --enable-checking=valgrind. The latter
would instrument the memory management inside GCC (and properly
handle the mmap end+1 thingy), so without it you would miss that
reused-pool-entries are actually uninitialized memory accesses.
