Possible compiler bug?

[OP1]

The following behavior illustrates a really weird behavior of IVF 10.1. As is, the subroutine compiles. If I comment out lines 2 and 15 of the subroutine, and uncomment lines 1 and 14, ifort spawns fortcom and then hangs. The only difference is the length of the variable name.

It took me quite a while to reduce the issue to this size.

Thanks for any help on this.

Works fine in the current version (12.1) of the compiler. I don't have 10.1 installed so can't readily check it. I suggest you move to a current, supported version.

Are you able to try this with a newer release of the compiler? There are no problems compiling it with 11.1.073 or 12.1.

[OP1]

Yes - problem solved with IVF 11.1.070 That was an odd bug though.

Thanks,
Olivier
