Synopsis: PD m4 (/usr/bin/m4) runs out of stack
State-Changed-From-To: open->closed

State-Changed-Why:
As Gregory Neil Shapiro <gshapiro@gshapiro.net> reminded me, this was fixed
(after 4.3 was released) with this change:
revision 1.10.2.2
date: 2001/05/24 20:52:13; author: gshapiro; state: Exp; lines: +9 -9
MFC: String operations could silently truncate long strings, leaving the output
corrupted. Mark's patch fixes this be removing the MAXTOK limitation on
substring operations and allowing the putback buffer size to be the
limiting factor. If the putback buffer size if reached, m4 gives an
error instead of silently truncating the string.
