- Subject: Crash on OSX 10.7 for Lua 5.2.2 on f:close()

Hi All,
I get a strange crash on OSX 10.7.4 running Lua 5.2.2 with this simple script:
print("Start", _VERSION)
local f = assert(io.open("test.dat", "wb"))
f:write("Hello")
print("Written hello")
f:close()
print("Closed")
The crash seems to happen on f:close(). I only get the crash when I
compile Lua with -arch i386. Lua 5.1.5 runs fine and Lua 5.2.2 runs
fine when compiled with (default) x86_64. If I remove f:close(), I get
no error. I tried to play with make options compiling it statically
and dynamically, but it always crashes if I compile with -arch i386.
make command: make MYCFLAGS="-arch i386" MYLDFLAGS="-arch i386" macosx
GDB output with a stack trace:
Start Lua 5.2

What am I doing wrong?
