Hello,
I changed the code to mnexcm, but it still crashes.
In fact, I tried this command before, it crashed, and I tried
the other one (mncomd).
The code:
Double_t PrintOutLevel = -1; // default no minuit output
if (DebugLevel)
{
PrintOutLevel = min(DebugLevel - 1, 3); // set minuit output level
(3=maximum)
}
Int_t ierr = 0;
gMinuit->mnexcm("set print", &PrintOutLevel, 1, ierr);
run-time error:

In the debugger I find a strange thing, the type of
PrintOutLevel seems to be va_list instead of Double_t;
(the type of ierr is OK: Int_t)
Is this maybe the cause of the crash?
And what causes this strange behaviour (I've had it before).
Is it the CC compiler, or the ld linker or what?
I hope you can clarify this problem to me.
Martin.
