Alright, Paul's suggestion was indeed spot on. DGLIBCXX_DEBUG was indeed causing my issues and appears to have been causing at least some of my issues with the developer version of fparser as well. I've known for a very long time that those flags simply didn't work with the Apple compilers, but I was surprised to learn that they don't appear to work at all on OS X even with the GNU GCC compilers. I'll work with Paul and one of us will make the appropriate changes to just strip those flags out universally on all OS X compilers inside of libMesh.
That error is eerily familiar to what I get on OSX when I use boost.unit in my app code. No resolution yet, but definitely let me know if you figure it out!

Is the pretty much settled at this point (i.e. ditching the non-release version of fparser) or is there still some more stuff y'all would like me to try?Don't know - libMesh may be off the hook! I have a patch ready to go that will support both the release and development versions of fparser and it seems to be working fine. I was able to configure and run libmesh 4.7 in debug mode and run the examples with my patch.MOOSE however is another story I'll have to continue to debug but I'm still running into some very bizarre errors that occur only in debug mode that simply don't make sense. I'll do a little more testing tomorrow and will probably commit this patch. For the record, the error I'm receiving (pointer being freed was not allocated) was one of the errors I saw repeatedly with the fparser stuff. Still investigating...Thanks,CodyIsn't the retina display bad ass?On Fri, Oct 19, 2012 at 10:32 AM, Cody Permann <firstname.lastname@example.org> wrote:

Interestingly on the same system in a different directory we were still able to reproduce the same issue when using HEAD. This gives me a little hope, I'm going to start looking at flags and other things to see what differences there might be between the two branches.OK, great. This was on my TODO list to look at this difference because the hiccup I was seeing in ex6 was fixed with using the the automake branch which means libtool is probably stripping out some incompatible flags or something at link time. I'll try and look at this tomorrow and let y'all know if I find anything.Well I'm the proud new owner of a new MacBook Pro (Retina Display) which will be nice to play around with while I figure out these compiler issues. Yesterday, Jason installed GCC 4.6 on it from source and it still failed to build libMesh in debug mode. I also had very weird issues with Clang for the first time ever so that wasn't a very nice start. As usual the hard drive comes from Apple partitioned with a case-insensitive filesystem so I'm going to blow it away, repartition the drive and start from scratch again today. This time I'm going to do all of the work myself to make sure Jason isn't introducing some odd bug in the process somewhere but at this point I don't think he is doing anything wrong. I'm debating on trying Mac Ports first to see if I can get something to work since I still haven't had time to look at those flags yet. If you learn anything keep me posted.For fun Derek and I did some compile time comparisons with GCC4.6 (opt mode) versus Apples GCC4.2 compilers on his Macbook pro (last year's model). It turns out that Apple's compilers are quite a bit faster than GCC even against my new hardware. I don't think he'll win though when I get clang going again. It's too bad that Apple had to break 'em.Thanks,CodyBest,Paul
