Help creating SHA256 altcoin with merged mining

[spencerdupre]

I'm trying to produce a SHA256 altcoin which is merge mined with Bitcoin.  I'd like to use some recent code, rather than base in on a 0.8.* or earlier codebase.  I've found this source:
https://github.com/sidhujag/bitcoin-0.9.2-Merge-Mining-fork

However, it's based on Devcoin, so it sends some of the mining proceeds to other parties.  I'm finding it very difficult to extract this feature, while keeping the merged mining.  For instance, in the miner.cpp file I've modified the CreateNewBlock function to remove the "Prepare to pay beneficiaries" section, but when I do so the compiled code segfaults.

Thanks to anyone who can help with this.

Could you upload the source code you have right now (modified) to GitHub?
