CLIPS 6.30 cores under Solaris 10

[Rob Moolhuijsen]

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

Any help would be appreciated.

Found the solution myself.

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

[Gary Riley]

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

Thanks this works perfectly.
