etime? and ifort problem (but not with ifc 7.1)

[vincentboucher]

Hello

Ifort (8) seems to have a problem when using etime (Vaxlib). This problem didn't occur with ifc version 7.1.

the following error message is

ifort -openmp -O2 -Vaxlib -W0 -WB -fpp2 -c cmbmain.f90
fortcom: Severe: cmbmain.f90, line 158: **Internal compiler error:
segmentation violation signal raised** 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.
actual=etime(tarray)
................^
compilation aborted for cmbmain.f90 (code 3)
make: *** [cmbmain.o] Error 3

the source code is available at http://camb.info/

Thanks,

Vincent

Since you appear to be writing an application intended to run on several platforms, it might make sense to avoid a non-portable function like etime(), when there is a standard alternative, cpu_time(). 10 years ago, of course, etime() would have been a reasonable choice, provided you documented it as system dependent.

It's difficult to follow your source, but you have declared etime() as external. To some compilers, that means "don't look for this in our library." In the Intel compiler documentation, you will see that the preferred way to declare such functions is with

USE IFLPORT

That doesn't exclude the possibility that the compiler may have a bug, particularly in the way library functions are called from internal subroutines. I am trying this out on a beta compiler, and may have a report to file. I would suggest you consider doing the same; there are enough versions of ifort that it would be difficult to guess which one you are using.

Which ifort? What does ifort -V display?

I can't find any reports of such a problem - if you are using a current version (8.0.046 or later) and still have the problem, please send an example to Intel Premier Support.

"ifort -V" give:

Intel Fortran Compiler for 32-bit applications, Version 8.0 Build 20031016Z Package ID: installpackageid

I can't fix the problem with IFLPORT and cpu_time.

I'm using a debian, the kernel release is 2.4.22-1-386

Interesting. Looks as if the compiler isn't installed properly. But I see it is an old one - the initial 8.0 release. If your license allows it, you should download a newer one from Intel Premier Support.

I filed premier issue Q253924 against the 8.1 beta Windows compiler, with respect to this application.
