Hmm, your code works OK for me and looks fine.
Can you provide some details:
Which OS
Which compiler
What are your compile/link lines?
What directory is your version of FLTK installed,
and how was it installed? (did you build yourself, or use a
package installer)
Perhaps it's a problem with the compiler or link flags.
Do you perhaps have multiple versions of FLTK installed?
If so, there might be crosstalk between the headers you're #include'ing
and the libs you're linking against that can cause perfectly OK code to
crash.
(in other words, you might be #include'ing headers from a different
version
of FLTK than you're linking against).
