Previous reports were from hrev57439 (a while back) new report is from hrev57966, the latest nightly as of reporting, both show the same bug but the ICU version is different since that got updated in the meantime. Like I said this bug has been happening for a while now, although r1b4 does not experience the bug.
The bug only appears in the live environment i.e. when you push the "Try it out" button, I have no idea why this is the case. Low memory issue is a red herring, of course you weren't testing with 256MB but I tested that in VMWare and it doesn't make a difference. Tested with 1, 2 and 4 virtual CPUs, no difference.
Maybe this is a VMWare issue? I haven't seen it on live hardware, only virtual.
I just checked and there's no crash on my real hardware (Lenovo X220) in hrev57966 live environment so this is indeed a VMWare thing. I'll update the description and lower the priority.
