# 
# I have been able to reduce the behavior to these simple test cases, which
# (unless I'm missing something obvious) should behave identically but don't:
# 
# $ printf '1,2,' | gawk 'BEGIN{RS="[,]+"}{print; a = getline; print "-"a"-"; print}'
# 1
# -0-
# 1

BEGIN {
	RS = "[,]+"
}

{
	printf "[%s] [%s]\n", $0, RT
	a = getline
	print "-"a"-"
	printf "[%s] [%s]\n", $0, RT
}
