Re: [Libmesh-users] [Libmesh-devel] XCode 3.2.2 + Intel 11.1 + OS X 10.6 + libMesh HEAD = Seg Fault

[Roy S. <roy...@ic...>]

Copying this to libmesh-users in case anyone there gets bitten by it.
Thanks for the warning!

So this looks like possibly an ABI problem?  Objects built with
XCode's custom g++ version not playing nicely when linked against
objects built with icpc?

After the update our libMesh based applications started throwing runtime errors (Seg. Faults).  As a troubleshooting step, I started disabling libMesh external dependancies and running the examples inside of libMesh but received runtime errors there as well.  There is some sort of negative reaction between recent Intel compilers and the new XCode  Application but I haven't seen anything specific popping up in the forums yet.  In fact the release notes for XCode specifically say "better support for the Intel icc compiler family".  At one place on the Intel site, one of the developers said they had been running the Intel regression tests against XCode and hadn't seen any problems yet.

There may be a bad interaction between our build and the Apple build but I just wanted to toss this apparent problem out there in case anybody else runs into it.  For now I have reverted back to XCode 3.2.1 which has fixed the problem.
