"\\[" as music function – stack overflow

[Simon Albrecht]

Hello,

when I start to compile the attached file, lily takes a long time for 
parsing and then exits with Microsoft’s "stack overflow/stack 
exhaustion" error code. I tested this with lily 2.19.8 and .15 and on 
both Windows and Ubuntu platforms with similar results. How does this 
come? and how to circumvent it?

Best regards,
Simon
