Edit: thats great you mined a block; I assume the reward came to a brand new key.
valgrind is for Linux isn't? Couldn't find a Windows version. Maybe this? http://www.codersnotes.com/sleepy/
I am not sure if coinbase-addr sends to the address I specify, but I'll have to keep checking. I also put a coinbase sig text. I think something is getting saved into the blockchain (according to chainz), but not the text I specified.
On the coinbase address, I see the issue with that - its preferring the address biblepaycore is sending (as if you started to solo mine) - I can fix that in the next version; but I have a question, when you say you injected a signature to be checked in chainz, what do you mean?
--coinbase-addr=ADDR payout address for solo mining
--coinbase-sig=TEXT data to insert in the coinbase when possible
So, when you specify a --coinbase-addr , you can specify a specific reward address to send to.
For my use case, different receiving would tell me which computer is mining rewards.
--coinbase-sig=TEXT in the raw output of the block, you will see your custom text included with mined block.
This is low priority. It is just a feature supported with minerd for bitcoin back when cpu mining was viable for bitcoin.
