ICE with -assume realloc_lhs

[Arjen_Markus]

Hello,

I am using Intel Fortran version 12.1.3 on Linux and with this program:

program lhs

integer, dimension(:), allocatable :: data

data = merge( (/2/), (/3/), data > 1 )

end program lhs

I get an ICE:

ifort -o lhs lhs.f90 -assume realloc_lhs

0_12459

: catastrophic error: **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.

compilation aborted for lhs.f90 (code 1)

(This is a trimmed down version of a program that actually does something useful ;))

Regards,

Arjen

Thanks, Arjen. I have escalated this as issue DPD200181153.

[Arjen_Markus]

You're welcome.

(I can work around it by not using the automatic reallocation feature)

I expect this problem to be fixed in a release later this year.

Note: I have been able to resolve the below issue by using compiler version 12.3.174.


Hi Steve,

I have a very similar problem: for a simple test program, -assume realloc_lhs does the trick to allow for automatic allocation. For a more complex program, using multiple source files, however, an error very similar to Arjen's is returned, except with error code 0_12032. The version is 11.1.072 - could an update help? Is this error code sufficient to identify a possible workaround, or would I need to submit more information?

Thanks,

Daniel

P.S.: I am running the compiler on a university server, and I don't own a license personally.

No, the error number is not sufficient. But 11.1 is now two versions old, and we have fixed many problems in the meantime. As you say you can use a newer compiler (that would be 12.0.3.174 I'd guess), then that's the solution.
