[Microsoft Visual C++ Runtime Library]

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.

Hello everyone:

I'm a relatively young (16 year old) programmer, trying to push myself to learn new things (somewhat an inefficient programmer tbh).

For the past week, I've been attempting to create a new Altcoin to learn about cryptocurrency, which I thought it was ready, but turns out after I released it, the coin got mined through easily and people started running into issues. I was using SHA256 (since the only stuff I know how to make so far is Scrypt and SHA256). Also, it was the old Bitcoin release ( 0.8.0 ), so it had issues there.

I'm still learning this whole cryptocurrency deal, trying to figure out how to code more efficiently for these, so please excuse my noobish questions:

What would be the best algorithm to use for a new Altcoin?

The list of algorithms I've heard of so far:

• SHA256
• Scrypt
• X11
• X13
• X15
• Lyra2RE

[RPC]

Coin has been delayed until I can figure out some errors, sorry.

Since both Pwnycoin and the original Ponycoin have been discontinued, I have been working on a revival of the two. My goals for creating Ponycoin are to learn more about cryptocurrency, while also providing a community-run coin for everypony (communities are great, right?).

Ponycoin is built off of the Bitcoin 0.8 wallet, but will be upgraded to the latest wallet over time. If you run into any bugs, please use the official Github page to notify me of any issues. Also feel free to make pools, if you desire.

Ports used by Ponycoin:
RPC: 6932 (Testnet: 16932)
P2P: 6933 (Testnet: 16933)



Windows (v0.8.0): Not built yet, will add soon. :L
Mac OS X: Not built yet, will add soon. :L
Github Source Code: https://github.com/ponycoin/ponycoin

PS: I know it's yet /another/ Altcoin, so please, spare the rant. Thank you.
