Hello,

The following is from one of the examples supplied with the ciao documentation. The computer setup is a 64 bit Debian based Mint 14 system.

There are no compilation errors; however, executing results in a segmentation error.

michael(a)14Mint64VM ~/CiaoDE-1.15-1685-g2d800d8/ciao/library/class/examples/geometry $ ciaoc geometry1 michael(a)14Mint64VM ~/CiaoDE-1.15-1685-g2d800d8/ciao/library/class/examples/geometry $ ./geometry1 Segmentation fault

Execution in a shell results in most of the predicates being undefined.

The segmentation error looks more like something caused by a 32 versus 64 bit system incompatibility. Any suggestions as to what to check to determine the source of the error?
