*** Break *** segmentation violation running simpleFitExample

[AbrahamReyes]

Hello everyone I'm trying to find why I have this segmentation violation when I run ./simpleFitExample the next that happens is this :

PARAMETER DEFINITIONS:
NO. NAME VALUE STEP SIZE LIMITS
1 mpv 4.00000e+01 1.50000e+01 0.00000e+00 1.50000e+02
2 sigma 5.00000e+00 3.00000e+00 0.00000e+00 3.00000e+01

** 1 **MIGRAD

FIRST CALL TO USER FUNCTION AT NEW START POINT, WITH IFLAG=4.

*** Break *** segmentation violation

There was a crash.
