Dear all,

I have come across another really strange bug in rpois.
If I do
sometimes it hangs, and hangs...
On my XP1000 alphaev6 workstation, it seems to happen more 
frequently than on other machines. I started a session on an older 
computer, and from the start, it looks like this:
[1] 1537190728
Error: syntax error [whoops, I'm usually using ESS]
[1] 1507263999
[hanged here, killed with ^C]
[1] 1463075843
[1] 1438068697
[hanging]

I think this is strange, because I've been doing this stuff 
a lot lately, but usually with a rather small parameter to the 
second rpois.  

Kjetil

On Intel, that consistently gives

I.e. signs of integer overflow. Apparently you partly get away with it
on a 64 bit machine, but I'm not surprised you get into regimes that
are not well tested by the poor developers working on hardware from
the bygone millennium....

:-) Whaddayamean "bygone", you're speaking to an astronomer here, you
know... :-) Anyway, if I can put my hardware to use, I'd be happy to do
so, just give me some detailed instructions.

Best,
