first run with -x to checjk the parse
ksh -cx 's="abbbc" ; d="${s/~(E)b{2,4}/dummy}" ; print -v .sh.match'
and it does show a problem
--
+t+ s=bbb
+t+ d='bbb/dummy}' <======
+t+ print -v .sh.match

we can double verify that the regex is ok by using the regex test harness
--
bin/package use
cd re
print $'K\t~(E)b{2,4}\tabbbc\t(1,4)' > t.dat
./testregex t.dat
--
so it looks like a battle between the 2 '}' in the ${...} expansion
