Bug ID: 117438
Summary: LO x64 - Remote Connection crashes with Execption in
"mscx_uno.dll"
Product: LibreOffice
Version: 5.4.6.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: framework
Assignee: [email protected]
Reporter: [email protected]
this problem seems to be x64 specific, cause "DocumentLoader.cxx" compiled
with LO 5.4.6 x86 SDK will work with a listening LO 5.4.6 x86.
steps to reproduce:
- compile "SDK Example DocumentLoader.cxx"
https://api.libreoffice.org/examples/cpp/DocumentLoader/
i used LO x64 SDK and VS 2015 (c/c++ options: /D "WIN32" /D "WNT"
/D "CPPU_ENV=mscx"), link with: /MACHINE:X64
- start LO x64 in listening mode, e.g.
"C:\Program Files\LibreOffice\program\soffice.exe"
--accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager
- start "DocumentLoader.exe" - it will connect but crash at:
Reference < XDesktop2 > xComponentLoader =
Desktop::create(xComponentContext);
Ausnahme ausgelöst bei 0x00007FFFED91EA70 (mscx_uno.dll) in
DocumentLoader.exe: 0xC0000005: Zugriffsverletzung beim Lesen an
Position 0x0000000000000008.
// Reference.hxx
inline XInterface * BaseReference::iquery(
XInterface * pInterface, const Type & rType )
{
if (pInterface)
{
Any aRet( pInterface->queryInterface( rType ) );
// Exception
if (typelib_TypeClass_INTERFACE == aRet.pType->eTypeClass)
{
XInterface * pRet = static_cast< XInterface * >( aRet.pReserved );
aRet.pReserved = NULL;
return pRet;
}
}
return NULL;
}
btw: i have another example, that will connect, load a document but crash
with same exception as soon as i try to get XModel from
xComponent = xComponentLoader->loadComponentFromURL(sAbsoluteDocUrl,
OUString(RTL_CONSTASCII_USTRINGPARAM("_blank")), 0, props);
if (xComponent.is()) {
// Exception
Reference < com::sun::star::frame::XModel > xModel(xComponent, UNO_QUERY);
}
