Thanks for the report!

I can reproduce at fileopen in a recent daily build:

Version: 24.8.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 92815f3a464b447898ecf52492247335228e4a72
CPU threads: 8; OS: Linux 6.5; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: CL threaded

...and 7.6.6, but not in 7.5.9 -> regression.

Also on Windows 11.

Bibisected with linux-64-7.6 repo to first bad build [1235fa4aa4d7ffa258bdffae06299ef14ce19016] which points to f1307f09e60e715877769e9fa12c0a6313fa0c1a which is a cherrypick of:

PoC patch

I attach a naive patch that solves the problem, but then this makes

make -C sw -sr CppunitTest_sw_core_layout CPPUNIT_TEST_NAME=testSplitFlyNestedRowSpan

hang, so this needs more time.
