I need advice on a problem with DLLs built for Excel using IVF 19.x. In particular, I want to confirm that the behaviour below is expected and not symptomatic of a more serious error. In IVF19, the debug version of the DLL does not build any more (it did in previous versions upto 17.x). I get the following error message (path, project and file names changed):
1>------ Build started: Project: MyExcelDLL, Configuration: Debug Win32 ------ 1>Compiling with Intel(R) Visual Fortran Compiler 188.8.131.52 [IA-32]... 1>file1.f90 1>file_with_dll_definition.f90 1>C:\MyPath\file_with_dll_definition.f90(295): catastrophic error: **Internal compiler error: internal abort** Please report this error along with the circumstances in which it occurred in a Software Problem Report.

However, in the Release version we do not have the same problem.

Will that my DLLs in Excel work only with /iface:cvf and Debug Multithreaded (/libs:static /threads /dbglibs) settings. Using the default settings causes Excel to crash unexpectedly. I will note that the Intel sample project works with default settings in both Debug and Release modes.
