": internal error: 010101_1

[Saran_T_]

I'm trying to compile Chombo on Mac OS X using the Intel compiler, however mcpcom fails after ~10 seconds, giving only the following error message

": internal error: 010101_1

This occurs whenever I try to compile at -O2 or above, but the problem disappears at -O1. Obviously this message is not very helpful to me at all as I have no idea what exactly is causing this.

The fully-preprocessed source file can be found here.

The exact compiler version is:

icpc version 15.0.1 (gcc version 4.9.0 compatibility)

The version of the LLVM/Clang toolchain used to setup the environment is:

Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)

Target: x86_64-apple-darwin14.0.0

Thread model: posix

-----

In case it helps, I also tried to compile the same file on Linux. The problem does NOT occur there. The compiler version on the Linux machine is:

icpc version 15.0.1 (gcc version 4.3.0 compatibility)

The gcc toolchain is:

Using built-in specs.

Because this is ICE and this kind of error description is probably not intended to be meaningful for compiler user.

Yes, however I thought someone from Intel might be able to provide extra info on exactly which line of code triggered this. I suspect this might be something in Clang's C++ library as I also managed to trigger the same error with a few other source files from Chombo.

I don't have access to Premier Support, so here is just about my only point of contact with Intel.
