Recent greps do not behave as documented with respect to after-context.  In=
 the past I've been accustomed to -AX meaning print X lines of after contex=
t.  That is not how gnu grep is working now, but it is how it is documented=
.  In fact -AX, which I tested with a v3.4 that I build on Ubuntu 18, will =
print X+1 lines of after-context.  If you want 1, you must say -A0.

In the past I've been accustomed to -AX meaning print X lines of after cont=
ext.  That is not how gnu grep is working now, but it is how it is document=
ed.  In fact -AX, which I tested with a v3.4 that I build on Ubuntu 18, wil=
l print X+1 lines of after-context.  If you want 1, you must say -A0.

Thanks for the report. Can you provide a stand-alone example like the
following to demonstrate the problem?
I am unable to reproduce it so far, since this prints only one line of
following context:

$ printf '%s\n' a b c d e | grep -A1 c
c
d
