<pre>I tried to use windbg more or less successfully and could have found the
problem.
It shows a access violation and a bucket id: NULL_POINTER_READ.
FAULTING_SOURCE_FILE:
C:\cygwin64\home\buildslave\source\libo-core\sd\source\ui\remotecontrol\Communicator.cxx
FAULTING_SOURCE_LINE_NUMBER: 87
This is the function
sdlo!sd::Communicator::execute+0x00000000000004a1
I think the line number is wrong or the source code I found has evolved.
The problem, I think, is in this line:
OStringBuffer aBuffer;
aBuffer.append( "slideshow_info\n" )
.append( OUStringToOString(
::comphelper::DocumentInfo::getDocumentTitle(
xFrame->getController()->getModel() ), RTL_TEXTENCODING_UTF8 ) )
.append("\n\n");
Before there are checks that xFrame is valid when it is used.
In this line there is no check and xFrame got de-referenced.
Is this correct?</pre>
