Hi,

I was executing this code '(2009/2000) ** (3958333/100000)' with the Pharo6.1 distribution and the vm crashed with she stack attached below. Tried it on both mac and windows 10. Seems that #raisedTo: has a special case for fractions that ends up calling #nthRoot: like '2009 nthRoot: 100000' leading to the crash.

The plugin is now fixed; see VMMaker.oscog-eem.2262. I'll generate code soon (am debugging something you're familiar with that takes several hours to run and don't want to generate sources while it's running). But I'm glad you've found a better way! This case creates 600k byte large integers and takes forever to run :-)

Nice! Thanks for the fix. Cheers, Andrei

Is there a way for this to get back into 6.1 - so we can shoot for a stable 6.x version that will last us for a year while 7.x is under development? I’m not familiar with how point release are handled in Pharo, and I get the impression that this is going to be a slightly rockier year as there have been some pretty revolutionary changes made to get us here. As its a vm change does this mean we get 6.2 queued up somehow? Tim

It’s a fair point - I guess if enough things crop up, then a 6.2 release gets contemplated. Tim

Hi Tim, I'd say: is this a showstopper? How often do you raise a Fraction to the power of another Fraction with large denominator (> 10000)? Or is it used indirectly by some kind of Framework?

If yes then open a pharo bug entry and mark for 6.x, else just wait 7.x...

We don't (yet) have a massive-cyber-corp backer, so with limited resources there are only limited point releases - usually only one, half-way to two-thirds through the year. But we already got 6.1, so I'm not sure affects things. Now the first rule is that fixes must go into the current dev branch and then backported. So get it into Pharo 7 and queue it up for (maybe) 6.2. cheers -ben
