Hi,

First I want to mention that I didn't see such an error with eta_c macros running 2000 events.

And I can here only speculate where it comes from.
So I guess that it could come not from the line 144 but from 143, where array of doubles is copied by element to array of float.

ein[i]=fCov[i];

And array of double is declared on line 134

Double_t fCov[15], fCovOut[15];

And I can guess that on some platforms it's initialised not with zeros but with rundom double numbers which exceed sometimes limits of float.

But it's only a speculation.

Dima
