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 :-)

Cheers,

Andrei
