Re: Crashing Strongtalk with a simple sample

Strongtalk reserves 50 mbyte of memory space (remember this VM is 10
years old). If you use more than what is reserved, you'll crash. You
don't need such a complex piece of code to trigger it, a simple Array
new: 20*1000*1000. is enough.

How to fix ? add:
ReservedHeapSize=1048576
to .strongtalkrc (the value is in kbytes. 1 GB here. default is
50*1024)
then your code will work (will take several minutes, be patient). But
because the oldspace GC isn't invoked automatically yet, if you
reiterate any huge allocation a few times without explicit GC, you'll
crash. After one iteration, heap grows to 384 MBytes here.

The result is 113321011323208.37 btw
