The end of array mark is added by lua52.pas, if you read the source code... My problem is solved if I remove the overloaded luaL_newlib function and use only the original pointer version, i.e.
var lib: array of luaL_Reg; luaL_newlib(L, PluaL_Reg(lib)); It seems that while converting from dynamic array to pointer, the compiler knows to point to the first element of the array, not the structure. Could anyone confirm this behavior? The remaining problems are: 1) why the lupas program works well even with the problematic overloaded version? I tested on Windows 7 (32bit), both programs failed. 2) I will email the author of lua52.pas to investigate the overloaded functions, and personally I will suggest to not use overloading at all.

I was already skeptic since the API doesn't mention the number of elements in the array as commonly required by a C function. -- View this message in context: http://free-pascal-lazarus.989080.n3.nabble.com/Lazarus-SEGFAULT-difference-between-pointer-and-dynarray-tp4028296p4028310.html Sent from the Free Pascal - Lazarus mailing list archive at Nabble.com. -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
