Created attachment 126079 [details] XLS file example When open this file (and many others, I guess they are made in one particular Excel version) Calc crashes.
On pc Debian x86-64 with LO Debian package 5.1.4, I don't reproduce this. For the test, could you disable OpenCL before opening any file? (Menu tools/Options/LibreOffice/OpenCL/, disable both checkboxes) Try to rename your LO directory profile (see https://wiki.documentfoundation.org/UserProfile#Windows) and give a new try. Finally, could you upgrade to 5.1.4?
5.1.4 fixes this! thank you!
Jury: thank you for your feedback. Since there's no specific fix, let's put this one to WFM.
