Hi,
I stumbled upon a possible bug in sed:
$ cat c
1
2
3
4
5
$ sed -n 'H;4,${g;D;h}' c # print the last 3 lines of a file
sed: couldn't re-allocate memory
Basically, if 'D' is used after 'g' or 'G' or 'x' (after copying from
the hold space), this realloc error is thrown. I think this is a bug.
Please let me know if this is a usage error on my part.
