StackOverflowException in Label.visitSubroutine

I get a stack overflow on a specific class with the attached program using ASM
3.1. What seems to trigger this is the visitLabel in MyMethodVisitor:22,
removing this line removes the error.

Excerpt of stack trace:
Exception in thread "main" java.lang.StackOverflowError
	at org.objectweb.asm.Label.visitSubroutine(Label.java:499)
