GDB indicates that flex (2.5.37 here) entered an infinite loop. The bug has
been reported on http://sourceforge.net/p/flex/bugs/151/ with a fix that worked
for me. Using flex version 2.5.35 does not produce a segmentation fault.

I got rid of this error by using bison 2.4.1 instead of 2.7.

Thank you for your help!
