Here's an even weirder case:.
Put following trivial input code:
for i=0,40000000 do pos(i,3,i) end
into a file called "bench.lua", and use it like:
./snogray bench.lua /tmp/out0.tga
Each call to "pos" will allocate a small userdata object, which is not
referenced by anything -- pure garbage!
With Lua 5.1.4 or LuaJIT, this takes about 30s, but only uses 4-5MB of
memory.
However with Lua 5.2.0, it uses about 3.4 _GB_ (and the system starts
thrashing). Something's definitely weird here...
According to valgrind (with a smaller loop count), there are no memory
leaks in either case.
Thanks,
-Miles
