Extremely long compile time with ifort 16.0.1 vs 15.0.3

Steve (or whoever gets this), we recently switched compilers from 15.0.3 to 16.0.1 and are now experiencing a significant (catastrophic) increase in compile time.  On a linux box, compile times went from 5 minutes to 40-50 minutes.  Are there any other reports of this?  I have given you our entire code in the past when we experienced this with 13 or 14 version compiler a few years ago (~4 years I think). Might be worthwhile to do something similar here.  Just wanted to get your take on it.

On a side note, we also see a few "*** glibc detected *** /usr/local/intel/compilers_and_libraries_2016.1.150/linux/bin/intel64/fortcom: free(): invalid pointer: 0x000000000469a060 ***" during compilation (and with version 15 compiler as well) but the code operation seems unaffected.
