Bug description: Crash after exit mai function
Description:
------------
A problem with php5activescript.dll
I created a new Win32 Console application in VisualStudio2005.
Everything runs fine until the very end. But after returning from function
main() the program waits some time and crashes.
So, it:
1. It unload slowly
2. It crashes
When doing the same with Python, PerlScript, JScript, VBScript there is no
problem after the function main exits. The program runs fine, invokes the
script dispatch functions, exits ok, quick and with no crashes.
BTW after the program ends, the engine unloads very slowly. Much slower
than other engines I tried Python, PerlScript, JScript, VBScript.
Reproduce code:
---------------
int main(){...CoInitialize();...{
IActiveScriptSite* pSite = new MyActiveScriptSite();
CComPtr<IActiveScript> pas;
CComPtr<IDispatch> pDisp;
HRESULT hr;
CComPtr<IActiveScriptParse> pasp;
hr = pasp.CoCreateInstance(L"PHPScript", 0, CLSCTX_ALL);
hr = pasp->InitNew();
hr = pasp->QueryInterface(&pas);
hr = pas->SetScriptSite(pSite);
EXCEPINFO ei;
wchar_t *pwszCode = L".... some PHP code in UNICODE format...
hr = pasp->ParseScriptText(pwszCode, 0, 0, 0, 0, 0,
SCRIPTTEXT_ISPERSISTENT,
0, &ei);
...
}
CoUninitialize();
Expected result:
----------------
I expect the engine to unload imediately, quickly and with no crashes.
Actual result:
--------------
A diallog box with a crash report is shown:
Unhandled exception at 0x011aa455 in eval.exe: 0xC0000005: Access
