Dear rooters,
I use TMinuit to minimize my function, and
my program crashes at the place which I don;t even know how to check. Here is the backtrace from gdb:
#0 0xb5c267bc in free () from /lib/tls/i686/cmov/libc.so.6
#1 0xb5e02d81 in operator delete () from /usr/lib/libstdc++.so.6

#10 0xb5e4d804 in TFitter::ExecuteCommand () from /home/slava/root/lib/libMinuit.so
#11 0x0805337d in main ()
The segmentation fault happens in my fcn function, which I’m attaching, between “after func” and “end of fcn” cout statements (basically, I can get rid of it, at least at the beginning of running, by eliminating the printout to the file, which doen’t seem to be a satisfactory solution).
Do you have any suggestions on what’s happening?
Best regards,
Slava.
