Created attachment 178634 [details] Sample document Steps to reproduce with a debug build of LO master: 0) decrease macro security to e.g. "Medium", so LO asks whether or not to allow macro executation 1) start Orca screen reader on Linux 2) start LO with the gtk3 VCL plugin 3) open attached document "UnoControlGrid.odt" (originally from https://bz.apache.org/ooo/show_bug.cgi?id=125322 ) 4) click on "Run the macro" Result: LO crashes with an assert: soffice.bin: .../libreoffice/vcl/source/app/dbggui.cxx:35: void ImplDbgTestSolarMutex(): Assertion `ImplGetSVData()->mpDefInst->GetYieldMutex()->IsCurrentThread() && "SolarMutex not owned!"' failed. This is on Debian testing with orca 41.2-1 and Version: 7.4.0.0.alpha0+ / LibreOffice Community Build ID: 5b03e07dd21b56e99d6b6b60edec1ed2f388bfc2 CPU threads: 12; OS: Linux 5.16; UI render: default; VCL: gtk3 Locale: en-GB (en_GB.UTF-8); UI: en-US Calc: threaded
I ran into this while working on something other a11y-related, plan to fix this along the way.
