Require fails - Error in ffi.lua

[FabbyD]

I get the following error:

th> require 'hdf5'
...e/fabrice/torch/install/share/lua/5.1/trepl/init.lua:384: ...ome/fabrice/torch/install/share/lua/5.1/hdf5/ffi.lua:56: expected align(#) on line 579 stack traceback:

Running Lua 5.1
Could it be that ffi.lua needs LuaJIT? If so, how could I work around that? LuaJIT has some kind of memory limit that makes the network I am trying to run unusable.

I have the same problem here. Any solution yet??

I happen to need to load a bunch of large json files and I am suffering from the same issue on Lua5.1/5.2. For those who need to bypass LuaJIT heap limitation, might want to try torch-tds. And call collectgarbage("collect") properly as a temporary solution.
