Re: [Quantlib-users] Python wrappers of FdmMesherIntegral and FixedLocalVolSurface

[Ruilong Xu <xur...@ho...>]

Hi,

I am reimplementing hestonslvmodel.cpp by Python.
SafeFdmMesherIntegral works well.
But SafeFixedLocalVolSurface may cause error in testAMoustacheGraph, the following is what I get:
double free or corruption (top)
Backend terminated or disconnected.Fatal Python error: Aborted
