    I downloaded the CLIPS_6.30_Beta_Windows_Application_Installer_R3.msi package and compiled it under Solaris 10 (SunOS 5.10) and cores when defining a "defclass".

    Details:
    uname -a
    SunOS sol10test 5.10 Generic_137111-03 sun4v sparc SUNW,SPARC-Enterprise-T5120

    Compiler:
    gcc --version
    gcc (GCC) 3.4.6

    Compiled everything under the "Projects/Source/CLIPS" directory.

    Execution:
    ./clipstest

      Found the solution myself.

      The flag "-O3" with tghe gcc compiler seems to cause the problem. Compiling with the "-O" works fine.

      Try compiling with -O3, but use the -fno-strict-aliasing option. This is from section 2 of the Advanced Programming Guide
