o.k. round2 I can try gdb(now that I have somewhat of an idea of
how to use one of these tools).

in the meanwhile hopefully this is useful(if not just clip, and I'll try
to gather something useful)


using this for valgrind and the command(below in log)
valgrind -v --tool=memcheck --leak-check=yes --num-callers=10
--leak-check=full --show-reachable=yes --gen-suppressions=yes
(log of valgrind is a bit long, so here's just a few of what
suppresions printed out:)

all I have to do is go into the directory
obj-x86_64-unknown-linux-gnu/js/src/

(I'll see what gdb does)
