I can observe it on all commits starting from b82fc3d. I'm running
32-bit Ubuntu, gcc version is 4.6.3.
Thank you for the bug report and the test case! Fixed in the git
repository.

I've pulled the fix and the segfault is gone, but the second test with
a spurious table still fails. Here is a slightly reduced version:
local function recurse(expr)
if type(expr) == "table" then
local t = {0}
for i = 1, #expr do
t[i] = recurse(expr[i])
end
print(t[2])
end
end
recurse {
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
{
{
{ 0, 0, 0 },
},
{
{
{ 0, 0, 0 },
{
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
{ 0, 0, 0, 0, 0, 0 }
}
},
0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
{ 0, 0 }
}
},
{ }
}
When using LuaJIT built from the latest commit (08e100e) it prints
several nils and a table, while it should only print nils (and so it does
with jit off).
