There is an extra line at the bottom on the development 
Seamonkey-2.53.22 page that is not on the 12.4 Seamonkey-2.53.21 page:

sed '/ZWJ/s/$/,CLASS_CHARACTER/' -i intl/lwbrk/LineBreaker.cpp

It puts an extra ",CLASS_CHARACTER" field in UnicodeLineBreakToClass[] 
which does not exist in ICU-77.1 I think.
