Description Caolán McNamara 2024-12-21 21:00:53 UTC 
Description:
There are a number of crashtesting documents which, when exported to rtf, cannot be reimported without asserting

Steps to Reproduce:
1. wget https://bugs.documentfoundation.org/attachment.cgi?id=73361 -O ~/Downloads/tdf59645-2.odt
2. ./instdir/program/soffice --headless --convert-to rtf ~/Downloads/tdf59645-2.odt
3. ./instdir/program/soffice --headless --convert-to pdf ./tdf59645-2.rtf

Actual Results:
#20 writerfilter::dmapper::DomainMapper_Impl::substream(unsigned int, tools::SvRef<writerfilter::Reference<writerfilter::Stream>> const&) at /home/caolan/LibreOffice/core/sw/source/writerfilter/dmapper/DomainMapper_Impl.cxx:10131
#21 writerfilter::dmapper::DomainMapper::lcl_substream(unsigned int, tools::SvRef<writerfilter::Reference<writerfilter::Stream>> const&) at /home/caolan/LibreOffice/core/sw/source/writerfilter/dmapper/DomainMapper.cxx:4747
#22 writerfilter::LoggedStream::substream(unsigned int, tools::SvRef<writerfilter::Reference<writerfilter::Stream>> const&) at /home/caolan/LibreOffice/core/sw/source/writerfilter/dmapper/LoggedResources.cxx:275
#23 writerfilter::rtftok::RTFDocumentImpl::resolveSubstream(unsigned long, unsigned int, rtl::OUString const&) at /home/caolan/LibreOffice/core/sw/source/writerfilter/rtftok/rtfdocumentimpl.cxx:381
#24 writerfilter::rtftok::RTFDocumentImpl::resolveSubstream(unsigned long, unsigned int) at /home/caolan/LibreOffice/core/sw/source/writerfilter/rtftok/rtfdocumentimpl.cxx:356


Expected Results:
reimport without assert


Reproducible: Always


User Profile Reset: No

Might not affect a non-dbgutil version without asserts enabled
Comment 1 Aron Budea 2025-01-30 06:32:56 UTC 
Confirmed with a local debug build of LO 25.8.0.0.alpha0+ (f3271cf5adfbe2e00d02417d85ff320763d7e9a5) / Windows.

This is the assert that fails:
// check that stacks are the same as before substream
assert(m_aContextStack.size() == contextSize);
