C/C++ execution error reporting #165

Open ProxyCausal opened 5 months ago

ProxyCausal commented 5 months ago

Is there any way to get the error code back from C/C++?

When running nloptr function R has been crashing for me and upon debugging it seems like the culprit is executing the C code solution <- .Call(NLoptR_Optimize, ret)

I suspect it's out of memory or numerical overflow issue, but it'd be nice to know for sure

Hello, @ProxyCausal. Would you please provide a reprex which demonstrates the same behavior?

@ProxyCausal, any further information, or may we close this?
