Segmentation fault on 2.3.1 OS X about cpuminer HOT 16 CLOSED

Could you please mail me (pooler at litecoinpool dot org) your exact configuration file and the output of minerd when you add "-D -P" to the command line options?

from cpuminer.

Okay. Note, I've just built the miner from source and so far (like 30 sec) it hasn't segfaulted. I will mail you shortly.

from cpuminer.

Running my locally compiled version seems to have 'cleared' the issue, I'll go back to the downloaded binary, tee the output and wait for it to segfault again and mail you that.

from cpuminer.

Another segfault on 10.7.5 on a different machine overnight using the downloaded binary. Restarted with -D -P and it took a little while but segfaulted again. Emailing you the dump.

Edit: 'screen' ate most of the dump. :/ Going to re-run in a terminal.

from cpuminer.

Two more segfaults overnight on 10.6.8. Can't get them to segfault again right out of the gate like with the first machine, so I'm running them all with -D -P and waiting, will send dumps when I get any.

from cpuminer.

Caught 3 on 10.6.8 and 10.7.5, Core 2 Duo and i5 CPUs. So far no problem on Linux. Emailing you hopefully-useful dumps.

from cpuminer.

So far on at least one machine, a locally-compiled version of 2.3.1 has run for a number of hours with no segfault. This is on the 10.7 machine. The binary is also 147180 bytes compared to the downloadable's 466492.

from cpuminer.

In case you are wondering, the size of the downloadable binary is due to it being statically linked to libcurl.

from cpuminer.

I figured static linking. I'm building it with an older xcode and homebrew - happy to do whatever I can to help debug. Just let me know.

A lot of my emails to you bounced after a couple days (litecoinpool.com???) - do you have what you need from me?

from cpuminer.

I only received two emails from you, one on June 21 at 18:12 UTC and one on June 22 at 20:28 UTC. Mind that the host part of my email address is litecoinpool.org, not litecoinpool.com as you wrote in your message above.
Anyway, I have just pushed a commit fixing a bug that can cause a segmentation fault on certain Stratum data, could you please try it out?

from cpuminer.

Would you like me to download the precompiled OS X binary? My local builds of 2.3.1 were all running fine.

from cpuminer.

Yes, please re-download the OS X binary here.

from cpuminer.

Done. Running, waiting for segfaults.

from cpuminer.

So far so good on the 10.7 box. Prior version would likely have segfaulted by now. Have not yet installed on the 10.6 boxes.

from cpuminer.

I think you nailed it. All of them are running fine now. Thanks for the amazing turnaround time on this bug! Really appreciated!
