So the debug info is corrupted...
Yep, thought so too..
Can you add this piece of code in
luaI_registerlocalvar (lparser.c:144, just before the return) and
see what it prints?
{ int i; for (i=0; i<f->nlocvars; i++)
printf("%d: %s ", f->locvars[i].varname; printf("\n"); }
Slightly modified:
printf("luaI_registerlocalvar() %s:%d; ", __FILE__, __LINE__ );
{ int i; for (i=0; i<=fs->nlocvars; i++)
printf("%d: %s ", i, getstr(f->locvars[i].varname)); printf("\r\n"); }
Got this:
> do
local test = {}
test.__index = test
function test:foo()
return self[1]
end
function test:func( idx )
local a, b, c = 1, 2, { foo = idx }
if idx.foo then return false end
return self:foo() + idx
end
function new_test()
return setmetatable( { 1, 2, 3, 4, 5 }, test )
end
end
