   summary:     Build JIT compiler by default, but do not enable it by

I don't understand how this could cause trouble for plotting,
especially if it the jit compiler is disabled by default.

Is anyone else able to reproduce this problem, or is it just me?

similar issue on cygwin
sombrero works but a clf immediately after crash

changeset:   17813:0a887758d1cc
summary:     fix compilation of main.cc on Windows

both on cli and gui.

   Program received signal SIGSEGV, Segmentation fault.
