Failure of generators generated with gevgen (18O with nu_e_bar, G21_11b, latest version of genie)

[WentaiLuo]

I used the latest version of genie that is producing nu_e_bar with oxygen 18 generators, the energy spectrum used is Kam's Atmospheric Neutrino Spectrum, which produces 1,500,000 events with energies of 0.01-1 GeV. when running up to 468897 there is an error reported, with the error being

gevgen: Spline.cxx:366: double genie::Spline::Evaluate(double) const: Assertion `!TMath::IsNaN(x)' failed.

Aborted

make: *** [Makefile:18: run_-12_1000080180_G21_11_b] Error
