Problem:

There is known defect where in some cases the results of a COMPUTE statement may be incorrect when executing in machine native code on Intel x86 platforms.

Resolution:

This error can be avoided by using the -g flag when compiling the machine native code executable.

The error is introduced by a incorrect assumption in the code optimization routine used by the compiler. The -g flag alters the optimization routines used by the compiler so that the error is avoided.

A permanent correction for this error will be released in a Fixpack for Server Express V4.0 SP3.
