Is this a compiler bug?

[Martin_Beizer]

When the attached code is built with VF 10.1, the correct results, shown below as #1, are output. When VF 11.1 is used, the incorrect output shown in #2 is obtained. Were only experiencing a problem when a function is called from within a subroutine.

Any ideas?

Thanks in advance!

For whatever this is worth:- I can reproduce this on WinXP64 VS2005, IVF11.1.054 in debug mode only. The release mode gives answer same as your #1.

It's a bug. For some reason, the compiler "forgets" the declaration of IP_GET as REAL in the host scope. A workaround is to disable Diagnostics > Check Routine Interfaces.

I will report this to the developers. The issue ID is DPD200149612.

Thanks! We set Diagnostics -> Check Routine Interfaces to No and the software works fine.

Also, thanks for the very fast response...

I expect this bug to be fixed in the next major release, scheduled for November.
