Maximum number of user-data

["Zé Pedro" <zarroba@...>]

I'm sorry to insist in this question but I'm really stuck in here. I have 27 types of data that I want to export to lua from C++. Everything was working until I defined my 18th data type. When I try to execute a script my program crashes with core dump while trying to reallocate memory. Here is the error:

*** glibc detected *** realloc(): invalid next size: 0xb4a0fcd8 ***

If I comment one data type definition the program doesn't crashes. Any idea on how to solve this problem?

Thanks,

Hi all..
I have a question about how many user-defined types can be registered in lua (or the size of memory allocated for it). I'm at a point when I register any more types there is a realloc exception when trying to execute a lua script. Have I reached the memory limit of data types registered?
Another problem I'm having is making variables that I pass from C to lua read only. I'm registering a variable that can be of one of three types defined by me. When adding it to the stack before I execute the script I've tried to redefine the "__newindex" field so the variable cannot be changed. But this isn't working. From what I understood I could only do this before I registered it. Any ideas?

Thanks,
