Hi Chen,
The changes to the code you've made change what it does and starts
mixing iterators from two different containers (that aren't event the
same type), so you've almost certainly broken the code.
It's a while since I wrote this particular code so exactly what it
does and how it's used escapes me right now - I'll need to do a wider
code review to uncover this. I really don't know whether there is a
bug here or not, lowering the amount of memory your system has
available will eventually introduce memory errors at some point - but
that would happen for almost all apps, a memory itself doesn't not
indicate a bug in the code that end up crashing at.
Could you please post a stack trace so we can analyse the issue
further, as well as info on exactly which VPB apps you are using, OS,
how much memory you set, etc.
Robert.
