Problem Note 14231: Segmentation Violation might occur when using Risk Factor Transformations in SAS® Risk Dimensions®
 |  |  |  |  |
In SAS Risk Dimensions, perturbing the same risk factor in an analysis and using a risk factor transformation might result in an error similar to the one below.
*
For software releases that are not yet generally available, the Fixed
Release is the software release in which the problem is planned to be
fixed.
Segmentation Violation In Task [ RISK ] Fault Occurred at [0x90000000260c3bc(?)] Task Traceback rskrun+0x38 -- bridge stub _uc_trampoline+0xfffffffffffffffc ERROR: Signal caught by CMP from PROC. NOTE: The SAS System stopped processing this step because of errors. NOTE: PROCEDURE RISK used (Total process time): real time 0.44 seconds cpu time 0.17 seconds
For example, assume there are 3 risk factors: a, b and c and there is a risk factor transformation defined to be c = a + b. If all three risk factors are in a covariance matrix used in a project running MC simulation, and the risk factor transformation method is selected in that project, then risk factor c is being perturbed by both the analysis and the rf transformation and the error will result.
