Can't install ruby gem (ffi) - Cannot allocate memory error

[melat0nin]

A brief description

Installing the Ruby gem ffi fails with a "cannot allocate memory" error. Seems related to some other issues which have apparently been fixed. I'm trying to install a jekyll website.

I have the same repo on a different box (both have 4gb of RAM), and it works fine there.

Expected results

Installation with no problems.

Actual results (with terminal output if applicable)

current directory: /mnt/c/Users/laurence/Code/tess/vendor/bundle/ruby/2.3.0/gems/ffi-1.9.14/ext/ffi_c /usr/bin/ruby2.3 -r ./siteconf20160817-4173-1h8ryfr.rb extconf.rb Cannot allocate memory - /usr/bin/ruby2.3 -r ./siteconf20160817-4173-1h8ryfr.rb extconf.rb 2>&1

Would it be possible for you to take an strace of the failing command so we can see where the failure is originating? Is it possible that an allocation is being performed that is lager than your NT page file?

[melat0nin]

Yes I believe the problem is to do with the NT page file. I manually increased it, which enabled me to run the command previously, but now I'm re-initialising this website (and its ruby environment) and it's not working this time round.

Here's the strace (sorry for the size). I think the problem is around line 12000.
