That's some nice detective work, I've run it through valgrind as well and
agree that that's where the leak is coming from. But, there really isn't a
lot we can do about it. Lua uses a 'C' style longjmp as the replacement for
a C++ 'throw' which does not call any C++ class destructors.
http://stackoverflow.com/questions/1376085/c-safe-to-use-longjmp-and-setjmp
I do notice (just now) in luaconf.h that if Lua is compiled with a C++
compiler it will use throw instead. This might be a solution for people who
compile the wxLua included Lua, but I don't think anything can be done with
an external default C compiled Lua. Nor is it obvious to me how to actually
control the LUAI_THROW, meaning if I build wxLua and #include Lua with a
C++ compiler, but the actual Lua lib was compiled with a C compiler, wxLua
will surely crash after the first Lua script code error. That makes things
very awkward. I suppose I can force the built-in Lua to be compiled as C++
and if someone specifies an exteral Lua lib in cmake, I'll use the C
compiler.
Your fix is about the best we can do, simply try to create as little new
memory as possible before the error. Actually, we might be able to do a
little better if we create a char* buffer on the stack and see if that gets
cleaned up by the longjmp.
The bottom line for you is to try to see if you can avoid the errors
altogether.
I will try a few things, but failing anything better will use your patch.
Thanks,
John
