ICE in latest IFX compiler

[Stephen_Sutcliffe]

The attached module code produces an ICE using the latest IFX compiler Intel® Fortran Compiler 2023.2.0 [Intel(R) 64] on Windows 11. The source consists of a single module file taken in isolation from a large project solution. I was getting the same messages when trying to compile the full solution plus a few similar relating to other modules though not all.

I've also attached the BuildLog.htm files showing compiler options for /MP=NO.

With /MP option set to Yes an additional message is output:

1>----- Build started: Project: BugReport (IFX), Configuration: Debug x64 ------

Build log written to "file://C:/Users/steve/Dropbox/General/BugReport/x64/Debug/BuildLog.htm"
BugReport - 1 error(s), 0 warning(s)

Errors such as these are the main reason for me not to move over to IFX from IFORT.

Can someone at Intel please have a look into this? Any feedback would be appreciated. Hopefully it will lead to fixes, that will enefit everyone, assuming problem is not a result of errant coding on my part.

Thanks

This ICE is fixed in the next compiler release. I just tested it with the latest 2024 and there is no ICE with IFX 2024, while there is with IFX 2023.2

Thank you for reporting this.
