This is still a problem with the latest upstream version: ; # 640 a’s ; letters="aaaaaaaaaa" ; letters="$letters$letters$letters$letters" ; letters="$letters$letters$letters$letters" ; letters="$letters$letters$letters$letters" ; mawk 'BEGIN {print "$letters$letters";}' Segmentation fault That is on i386. You might need double the length on a system with 64-bit pointers. This is not fixed by the patch in http://bugs.debian.org/391051 but could be fixed by something similar. As with that bug, I think the check should be <= SPRINTF_SZ - whatever. Thought you might like to know. Cheers, Jonathan
