[Gmsh] crashing of gmh 3.03

[walter steffe]

Hello
 I am experiencing a crash with the last version of gmsh.

The segfault happen when I push update bottom on the mesh statistic (as
required to see SICN,Gamma,...).
Gmsh was built by myself on Ubuntu 16.04 following the usual procedure
(mkdir build, cd build, cmake .., ccmake .., configure, make, sudo make
install). No change in the default setting of cmake config. 

The problem was not present in gmsh 2.16 (the version I was using
before)

Following is the trace of GDB. The fault seems to be related with
libfltk 1.3. But libfltk 1.3 worked properly with gmsh 2.16.
