This is a bug in the compiler itself and nothing to do with Amber other than
the fact that that specific file is obviously laid out in some way that
makes the compiler try to do a specific type of optimization during which
the compiler segfaults. See if there is a newer version of the Intel
compiler available on The one they give you for download
on the regular site is often not the latest version. If you have the very
latest version you may want to consider submitting a bug report to Intel.

All the best
