You need to run the updated instructions at:
https://linuxfromscratch.org/blfs/view/svn/xsoft/seamonkey.html (Sysv)
or https://linuxfromscratch.org/blfs/view/systemd/xsoft/seamonkey.html
(Systemd). Specifically, the following operation got changed from:

(for i in {43..47}; do
    sed '/ZWJ/s/$/,CLASS_CHARACTER/' -i intl/lwbrk/LineBreaker.cpp || 
exit $?
done) &&

to:

(for i in {43..48}; do
    sed '/ZWJ/s/$/,CLASS_CHARACTER/' -i intl/lwbrk/LineBreaker.cpp || 
exit $?
done) &&

The above error suggests there's an extra or missing CLASS_CHARACTER,
creating a mismatched array size with ICU. This can be a result of
running outdated instructions or a mistyping of instructions.
