Hi,
I'm running a very long fit program that uses TMinuit and a private fit
function. My function makes extensive use of TMatrixD and the inversion
functionality, in fact I got worried and made my own TMatrixQ that uses
"long double" everywhere instead of Double_t. Although I can run
smoothly with a few parameters (say, six to make a 3x3 symmetric matrix)
when I go up to 190 parameters (10x10) I get this mysterious message:
Aborted
Not very informative! No idea what routine or why. I have performed
"grep Aborted */src/*.cxx" and "grep Aborted */inc/*.h" in the ROOT
directories without finding a single candidate routine. It takes
several hours of running my fitter to reach the terminal message, so
debugging would be tedious to say the least. My investigation shows
that the fit is progressing and my function is called >5000 times before
I get the crash.
Does anybody know the origin of this "Aborted" message? I don't
understand how it can hide from me in the source code. I am happy (I
guess) that I get a "graceful exit" from the executable, but I wish I
knew how to prevent it. The fit looked like it was going to work...
