[Wien] Intels Oneapi 2024: Compiler bug ?

[Peter Blaha]

Dear users,

Maybe there is a Fortran expert who knows if this syntax is correct or not.

A user reported recently a compilation problem using   the most recent 
ifort (or ifx, which will become soon the new fortran compiler) 
(oneapi-2024.0)   in SRC_wplot:

ifx -O -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML -traceback 
-assume buffered_io -I/home/aarav/intel/mkl/2024.0/include 
-DHAVE_PTR_ALLOC_GENERICS -Ilib -free -gen-interface nosource -traceback 
-g -I../SRC_w2w/lib -I../SRC_w2w/lib -c modules.f -olib/modules.o 
-module lib
modules.f(195): error #6911: The syntax of this substring is invalid. 
[CART]
        inw%grid%len = (/( sqrt(sum( inw%grid%Cart(:,i)**2 )), i=1,3 )/)
---------------------------------------------^

So the error is in line 195 of SRC_wplot/modules.f.

It appear ONLY with the most recent oneapi 2024.0, not with older 
versions nor with gfortran-12.

Thus the question is: Is this a compiler bug or is this due to a very 
new fortran-standard which this version enforces ?
Has anybody an even newer gfortran (higher than version 12) and can test 
it with this compiler ?

Best regards
Peter Blaha
