The fink Lua packages (lua51 and lua51-dev) are now up-to-date also in
This means they are good for multithreading.

Your problems should be due to having two separate copies of Lua
core in the system. Try to make sure lua the command line
executable is really dynamically linked to the lua shared library
that extension modules use.
There may also be other ways to guarantee this singularity of the
Lua core. If you have two cores and you do multiple threads, OS X
gets confused like you showed.
For users of Lua via the fink distribution, make sure your package
is >= 5.1.1-14. That has the necessary changes. Unstable has a
recent one but stable still lags behind in 5.1.1-4 or so. Lanes does
not work fine with that.

I tried to experiment with LuaLanes, but have some problems on my
Snow Leopard installation.
Every time I try to run one of the test I get an malloc error like
lanes-2.0.3$ LUA_CPATH=./src/?.so LUA_PATH="src/?.lua;./
tests/?.lua" lua tests/recursive.lua
depth: 0 1 2 3 4 5 6 7 8 9 10 11
lua(61739,0x7fff71085be0) malloc: *** error for object 0x1000ad1a0:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
I tried to use luarocks from MacPorts to install lanes, but there
is no rock spec. for the latest version, and for the 2.0 version,
the download is gone, so it just failed installing.
Furthermore, I followed the hints in the README to compile Lua
with LUA_USE_DLOPEN and LUA_USE_POSIX as well as using a dylib for
the core and library code, as described.
However, I am still ending up with the error given above.
Any thoughts how this could be fixed?
Many thanks and best regards
BTW: On an Ubuntu, it works fine...
