emu crash

there's a nasty bug either somewhere in emu or the inferno ps
command.  the following causes emu to hang completely on at least
linux and macosx:

% for i in 1 2 3 4 5 {ps > /dev/null}

(sometimes it takes a few consecutive attempts)

another user on #inferno was able to reproduce this as well.  emu
running under plan 9 or windows doesn't appear to exhibit this
problem.

Caerwyn suggested a bug in prog(3) and the following tends to support
that:

Re: emu crash

i think it's a surprisingly old problem i repaired recently,
but since i'm now having trouble reproducing it without the
fix, i'll need to fuss with it a bit more ...
(i could reproduce it, though, from time to time)

Re: building under macosx

i've finally fixed that.  i'd been looking in completely the wrong place for it,
partly because it actually was wrong on all platforms (as i'd normally expect),
not just Linux or MacOSX, but manifested itself differently enough to escape
the fatal error on some other platforms (but generate rubbish sbl entries).
it was actually a bug in creating function references.  the resulting code
was correct but the source reference was not.  i just now had a better example
that made it quite obvious.

if it causes trouble before the next .iso is out (shortly),
apply the one line fix:

/n/dump/2005/1017/usr/inferno/limbo/ecom.c:1229 a /usr/inferno/limbo/ecom.c:1230
> 			tr.src = *src;

(the following line is tr.op = Oind, for context)

out of interest, would this version also run under Windows 2000/XP/... ?

seen it work.

Some questions regarding Limbo/Tk

Hello everybody,

I've got some questions with regards to Tk. First of, "A Decent into
Limbo"[0], section 2.2 has a Tk-example which does:
	t := tk->toplevel(ctxt.screen, "");
Which makes my Limbo (I installed from some CD I found, labeled "5th
edition" unhappy:
hw.b: 18: tk->toplevel: argument type mismatch: expected ref
Draw->Display, saw ctxt.screen of type ref Draw->Screen.
Piece of cake, I changed it to:
        t := tk->toplevel(ctxt.display, "");
Which makes it compile, however the 1-to-1 copy of the 2.2-example (in
short, a button labeled {Hello World}) does not work. 
So what is the problem? Version mismatch, old/wrong documentation? What
am I doing wrong? 

Mfg, Sascha Retzki
