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.
