Delay() and Timer() functions cause core dumps in standalone executable

[LJM]

The Delay() and Timer() functions cause my program to core dump. I'm using CVI 5.0 on Solaris 8 on a SunBlade150 workstation. The core dumps only occur when running the standalone executable. If I run the program in debug mode, it runs fine.
Example:
{
puts("Start");
Delay(1.0);
puts("End");
}
