Segmentation violation while returning from Matlab function

I have a c shared library built from a matlab function. The function executes properly till end but segmentation violation occurs on returning.

Abnormal termination:
Segmentation violation

Register State (from fault):
  EAX = 00000004  EBX = 0026ac14

I'm calling this in c as :

 mlfRecognizeface(1, *&Recognized*, mat1, LeftEyeFilterAverage, RightEyeFilterAverage, NormImgSize, BunchGraph, BunchGraphPolar, GaborMask, Masks, DatabaseFaceGraphFront, DatabaseFaceGraphPolarFront, SimilarityThreshold, DatabaseFaceGraphRight, DatabaseFaceGraphPolarRight, DatabaseFaceGraphLeft, DatabaseFaceGraphPolarLeft, Edges);

where Recognized is the only output and all of these are of type mxArray

Hi

I am having this problem too, have you managed to resolve it?

Answer 3

Hi,

seems like you are running your application out of a folder where you dont have read permissions. Please try to run your program from a folder with read permission.

Does this help or do you still get the same error?
