Different behaviour when using simbody RelWithDebInfo vs Release 3.7

[apalazzi]

Hi,

I'm refactoring my program, and I have a strange behavior: if I use the (dynamic) libraries created with RelWithDebInfo it ends with an error "free(): invalid pointer", but if I run the debug version the error is different:

/home/andrea/simbody/simbody/SimTKmath/Geometry/include/simmath/internal/GCVSPLUtil.h:95: static SimTK::Vec<MM, double, 1> SimTK::GCVSPLUtil::splder(int, int, SimTK::Real, const Vector&, const SimTK::Vector_<SimTK::Vec<MM, double, 1> >&) [with int K = 1; SimTK::Real = double; SimTK::Vector = SimTK::Vector_<double>]: Assertion `t >= x[0] && t <= x[x.size()-1]' failed.

I tested different build options (-Ox, -gx, -DNDEBUG) but the result is always the same: the program using RelWithDebInfo aborts on free() while with Debug it fails the assertion.

Let me know if you need me to test something specific.

Are you building your client project with the same flags as those with which you compiled Simbody?

I didn't specify any flags while compiling Simbody, the build system did all the job; moreover neither the readme nor the document linked at "you want to... use simbody in your own program" - aka SimbodyAndMolmodelUserGuide.pdf - says anything about flags or defines to be used during compilation of my program.
