Bug ID: 172066
Summary: Calling XCloseable::close via UNO Remoting Causes a
Crash
Product: LibreOffice
Version: 26.2.3.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer
Assignee: [email protected]

C++ sample program with CMake project to demonstrate crash
Calling XCloseable::close on a Writer document from another application will
cause LibreOffice 26.2.3.2 to crash and generate a crash dump on Windows 11
24H2. This was still possible with version 25.8.6.2. The following C++ sample
code will trigger the crash:
#include <sal/main.h>
#include <cppuhelper/bootstrap.hxx>
#include <com/sun/star/frame/XComponentLoader.hpp>
#include <com/sun/star/frame/XDesktop.hpp>
#include <com/sun/star/util/XCloseable.hpp>
#include <com/sun/star/uno/XComponentContext.hpp>
#include <iostream>
using namespace com::sun::star;
using namespace com::sun::star::uno;
SAL_IMPLEMENT_MAIN_WITH_ARGS(argc, argv)
{
try
{
Reference<XComponentContext> context = cppu::bootstrap();
Reference<lang::XMultiComponentFactory> smgr =
context->getServiceManager();
Reference<frame::XComponentLoader> loader(
smgr->createInstanceWithContext("com.sun.star.frame.Desktop", context),
UNO_QUERY);
auto doc = loader->loadComponentFromURL(
rtl::OUString::createFromAscii("private:factory/swriter"),
rtl::OUString::createFromAscii("_blank"),
0,
Sequence<beans::PropertyValue>());
// Calling close with LibreOffice 24.2.6.2 and 25.8.6.2 works
and the program will
// terminate successfully. Calling close with LibreOffice
26.2.2.2 and 26.2.3.2
// cause LibreOffice to crash and generate a crash dump.
Reference<util::XCloseable> closeable(doc, UNO_QUERY);
if (closeable.is())
closeable->close(true);
Reference<frame::XDesktop> desktop(loader, UNO_QUERY);
if (desktop.is())
desktop->terminate();
}
catch (Exception& e)
{
std::cerr << "UNO Exception occurred: " << std::endl;
return 1;
}
return 0;
}
