Bug ID: 118180
Summary: Assertion failed opening an XLSM with
Application.ScreenUpdating set to true
Product: LibreOffice
Version: 6.2.0.0.alpha0+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: ba...@caesar.elte.hu
Blocks: 105537, 108908

Sample XLSM
Open the attached XLSM file in a debug build, with having macros enabled. It
has a simple macro function that sets:
Application.ScreenUpdating = True
If the macro is called in a number of rows, the following assert is triggered
when opening the file, in ScDocument::UnlockAdjustHeight():
assert(nAdjustHeightLock > 0);
https://opengrok.libreoffice.org/xref/core/sc/source/core/data/document.cxx#1799
No assertion failed if Application.ScreenUpdating isn't set to true.
Interestingly, there's no assertion if spreadsheet only contains 3 rows with
the call to the function, but there is when it contains 4.
Observed using an LO 6.2 master build
(06014f7a23bbc26c7e3d3b9c0bd4dd972f514433) / Windows 7.
