ifx compiler crash when trying to ICHAR a string of dimension >1

[Frankcombe__Kim]

On compiling using ifx 2024.02 with debug settings

-c -m64 -check all -debug full -traceback -warn all -heap-arrays -stand -standard-semantics

I get the following

/home/kim/code/gmagtool/gem19in.f90(442): error #5623: **Internal compiler error: internal abort** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error.
ZDATA(IMTRG2)=REAL(IACHAR(TRIM(TEMPSTR)))
-----------------------------------^
compilation aborted for /home/kim/code/gmagtool/gem19in.f90 (code 3)

TEMPSTR is declared as CHARACTER(LEN=80) BUT on this occasion I know it will only have a trimmed length of 1. I'm using the variable for many reads so would like it long enough for all occasions.

recasting to ZDATA(IMTRG2)=REAL(IACHAR(TEMPSTR(1:1)))

works and allows compilation.

I guess rather than a string of hex a simple warning that IACAR is meant for CHAR*1 would be nice.

No doubt the same as this one https://community.intel.com/t5/Intel-Fortran-Compiler/Internal-compiler-error-with-ichar-intrinsic-function/m-p/1635985#M173888

Yes, same issue.  Thanks Andrew!
