The update 1 and initial release of ifort v16 are leading to a catastrophic error during the compilation of a large fortran code (>100kLOC) while everthing is ok with v15.x.
For the same code, v15 takes about 5min to compiler the entire code and v16 try to compile during several hours, and then crashes (the same compilation option being used).
So there is definitely something going wrong with v16.
The problem is, I have no way to make a short reproducible example.
Moreover, I do not have an intel premium account.
