Tried putting in the printf statement in new_gl_handler but it didn't
appear when I ran analysis (or when it crashed).
Also tried putting the bit of code in draw_text_gl_handler but I got a
compilation error:
gl_handler.c:947: error: `argc' undeclared (first use in this function)
gl_handler.c:947: error: (Each undeclared identifier is reported only once
gl_handler.c:947: error: for each function it appears in.)
gl_handler.c:947: error: `argv' undeclared (first use in this function)
