Mutex is 0xdddddddddddddddd:

sal3.dll!osl_acquireMutex(_oslMutexImpl * Mutex) Line 66

swuilo.dll!`anonymous namespace'::setValue(weld::Label & rWidget, unsigned
__int64 nValue, const LocaleDataWrapper & rLocaleData) Line 47
        at C:\lo\src\core\sw\source\ui\dialog\wordcountdialog.cxx(47)

        at C:\lo\src\core\sw\source\ui\dialog\wordcountdialog.cxx(62)
swuilo.dll!SwWordCountFloatDlg::UpdateCounts() Line 146
        at C:\lo\src\core\sw\source\ui\dialog\wordcountdialog.cxx(146)
swuilo.dll!AbstractSwWordCountFloatDlg_Impl::UpdateCounts() Line 748
        at C:\lo\src\core\sw\source\ui\dialog\swdlgfact.cxx(748)
swlo.dll!SwWordCountWrapper::UpdateCounts() Line 41
        at C:\lo\src\core\sw\source\uibase\dialog\wordcountwrapper.cxx(41)
swlo.dll!SwView::UpdateWordCount(SfxShell * pShell, unsigned short nSlot) Line
215
        at C:\lo\src\core\sw\source\uibase\uiview\view1.cxx(215)

        at C:\lo\src\core\sw\source\uibase\shells\textsh1.cxx(1392)
...

which means that the mutex in rLocaleData, which was already successfully used
in SwWordCountFloatDlg::SetValues for m_xCurrentWordFT, got deleted (hence
0xdddddddddddddddd in debug build) and crashes when processing
m_xCurrentCharacterFT ...
