Just tried out v17 update 1 and now I get an internal compiler error part way through my compile. I already understand that I need to provide the offending code but the compiler error is somewhere in a very long fortran source file in the middle of a semi-large fortran project. All I know is that the initial release of v17 didn't have any issues with the same project. The source file is 3643 lines long and is part of a DLL library that has over 50 source files. So not really sure how to proceed with diagnosing the issue in order to get more information the developers behind IFORT.
