=============================== In his response to my message "TT512 Rebuttal" "gjs@k.cs.cmu.edu" (Gregory Stein @ Carnegie-Mellon University, CS/RI) asks Dave Winer to explain the ROM bug. He posted the following message of explanation in the Macintosh conference of BIX (tm) (Byte Information Exchange). I co-moderate that conference and am gatewaying it in the interest of (I hope) all. >========== >macintosh/net.mac #212, from dwiner, 735 chars, Thu Jun 5 14:06:05 1986 >Comment to 211. >---------- >Look - I can't make up for the fact that I am not a Macintosh programmer. >I can only pass on what I was told from someone whose judgement I trust >implicitly... > >"On an original Macintosh or a Mac XL running Macworks, 'the heap' is too >close to the stack when //any heap// is too close to the stack.
