Let me reply to myself, maybe it will be useful for someone. I use Windows
Server 2022. I tried all variations of Cygwin and findutil versions. I even
moved xargs.exe from a known working setup. The error was always the same
as above. Finally I built xargs from source and added debug fprintf. When
xargs was invoked from the command line, bc_ctl.arg_max was  24025, when it
was invoked from the build it was 1428 and assertion failed. I did not find
a reason for this behaviour. I removed the assert from the code, and the
build of LibreOffice help succeeded with this modified xargs.exe.
