Looks like it's bug 1426574 and it's fixed in version 64.

Just installed the 64 version. Hope it helps ...

Just crashed again:

This is sth different. You've allocated the whole memory.

How much do you have RAM in total? 2GB?

4GB in total

Ahh, it's Win10 x86. I can't say anything about it, no idea.

What is your current size of the Windows page file?

I see in the crash report: virtualMaxMB : 2048 So maybe try to increase the size of the page file to the recommended size to see if that makes a difference.
