[Programming Help] - CPU Exception when building for debugging but not release?

I'm getting a CPU Exception from one of my studies ... but only when I build it for debugging. Does this make sense? I don't have any code branches between debug vs release so the actual code being compiled should be the same. I'm restarting SC between rebuilding to be sure but am still experiencing the CPU exception on a debug build. Any "pointers" ;)?

Try attaching the debugger to the SierraChart process before opening the chart, or attaching the study. The debugger should then give you more information on the issue before the CPU exception error is logged. |

If you are using Visual Studio, try updating to the latest release. I have experienced the opposite situation - fine in Debug (which in turn disables code optimisation and adds padding to avoid stack corruption) but nightmare errors in Release mode. It turned out that the build of Visual Studio I was using had a bug causing bad code to be generated but only in release mode. Un-bloody-believable. |

Thanks for your suggestions! I think the issue at my end ended up being how delete was handled between a release vs debug. It appears as though when compiling for release, surprisingly, delete set my pointer to null (that's my guess) while for debug it didn't (when later parts of my code was setting the pointer to a new value when the pointer was null, and had assumed delete previously implicitly set the pointer to null.
