To start with the obvious, did you run the program under gdb and get a

I ran the program in Netbeans 8.0

This doesn't answer my question; your editor/IDE is immaterial. I don't mean to be blunt, but if you want some help with the problem, you'll have to provide some useful information we do something with. Run the program with a debugger and get a stacktrace. Print the values of name and m in the stack frame calling TIFFopen, and in the frame for TIFFopen. Find which caused the segmentation fault, and look at the source to see why it got one or both of these variables into an invalid state.

If you can, point us to your source code so we can have a look.
