Could somebody please explain the following:
// test.cpp
extern "C" __declspec(dllexport) int luaopen_test (lua_State *L)
{
char *buf = new char;
delete buf;
lua_newtable(L);
return 1;
}
I do the following:
luajit.exe -ltest
LuaJIT 2.0.3 -- Copyright (C) 2005-2014 Mike Pall. http://luajit.org/
JIT: ON CMOV SSE2 SSE3 fold cse dce fwd dse narrow loop abc sink fuse
Then I press CtrlZ Enter and get an exception message box:
----------------------------------------------------------------
luajit.EXE - Application Error
The exception Breakpoint
A breakpoint has been reached.
(0x80000003) occurred in the application at location 0x10003c38.
----------------------------------------------------------------
Details:
* MinGW toolchain was used (g++ 4.7.1 or 4.8.1 - no difference).
* Exception occurs only if operator `new` was called and it occurs
on luajit.exe exit, rather than at the time `new` was called.
* Windows XP SP3 x86 -> EXCEPTION.
* Windows 7 x64 (but same 32-bit binaries) -> OK.
* Windows XP + lua.exe (PUC-Rio) + lua5.1.dll (PUC-Rio) -> OK.
* Windows XP + lua.exe (PUC-Rio) + lua5.1.dll (LuaJIT) -> OK.
Summary:
3 factors are needed to cause the exception:
1) call operator `new'
2) luajit.exe (lua.exe is OK; DLL doesn't matter)
3) Windows XP (Windows 7 is OK)
Thank you.
