cpuminer with MacMiner 1.4.5 broken on OS X Lion

[XFox]

•Issue•
I tried to run the cpuminer binary included with MacMiner 1.4.5 on a Mac with OS X Lion 10.7.5 and an Intel Core 2 Duo CPU but it didn't work, as soon as I click "Start" I get a crash report.
If I try to check cpuminer version from the command line with

Code:

$ /Applications/MacMiner.app/Contents/Resources/minerd --version

I get a rude Segmentation Fault error.

•Solution•
Download the latest cpuminer OS X binary from the project's download page.
At the time of writing the latest version is v2.3.2 and the direct download link is:
http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2-osx64.zip/download
Uncompress the ZIP file and move the resulting minerd file file into the /Applications/MacMiner.app/Contents/Resources/ folder (overwrite the existing minerd file).
Unfortunately this doesn't completely fix the issue and if you try lo launch cpuminer from MacMiner it will crash after a few seconds, use Terminal.app with the following command instead

Code:

$ /Applications/MacMiner.app/Contents/Resources/minerd -o http://host:port -u username -p password -t thread-count

where thread-count is the number of cores you have (double that if you have Hyper-threading).

•Disclaimer•
I would have been happy to post in the official MacMiner thread but this happens to be my first post on the forum. I searched the forum and it seems this has not been reported yet.

Are you trying to mine with a cpu?

I'm guessing the issue has not been reported because hardly anyone (if anyone at all) mines with cpus anymore.  The efficiency is terrible, and a lot of pools can't accommodate cpu mining because of how slow it is.

Well, that's what cpuminer is intended to do, it mines LTC with CPUs.

I don't doubt it but if you look at the official MacMiner thread you'll notice recent posts about cpuminer, so at least for fun and/or educational and/or experimental purposes it's still run by some users.
Indeed, a very recent MacMiner beta has been released to fix issues with cpuminer but on my system it doesn't seems to do the trick.
