Altcoin-qt Wallet Runtime Termination on Close

[x86cam]

So I've been trying to make a coin for fun recently, but I'm stumped on this issue.

On Windows, the wallet works fine: I can mine from a pool, coins gets sent, I can also transfer coins, etc., but when I close the wallet (clicking the X button/File + Close), I always get a whole bunch of errors from Microsoft Visual C++ Runtime Library:

If the picture doesn't load, the errors all say:

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

When I close one of those errors, the whole thing stops responding and crashes.

I have no idea what the issue is here, the log file only says this:

I'm developing on a Ubuntu 14.04.1 VM, in which on Ubuntu, the wallet works without issue. Also, the coin daemon (Xcoind.exe) works fine on Windows, no issues.

Here is my .pro file: http://pastebin.com/5ffptXxT

To compile, I used this thread: https://bitcointalk.org/index.php?topic=149479.0

Any suggestions?

EDIT: If it may help, I am using the 0.8.6 source forked from BTC, but with the X11 algo.

Also, I discovered that when I try and type in an RPC command, it does the same exact thing (but with only one error):

Any help I could get on this?

I would recommend that you do any windows or mac builds with the gitian build system. It lets you deterministically build all of the binaries on a linux system like the one that you are developing in.

Question is: how would I use the gitian build system when there only are a few folders (contrib/gitian-descriptors [and] contrib/gitian-downloader)?

There is more to it. I can teach you how to do it. It will work for pretty much any coin that is based off of Bitcoin in some way. There is more to it and it takes some time to make it work properly, but in the end it makes compiling across platforms so much easier.
