LeakSanitizer error

I tried to run nrop against the example executables in the examples directory, and I get the following error:

Found Entry @4000b0
Setting NULL chunk
0x0000000000400000: jnle 0x400047 ;

@awailly Did you get a chance to look into this?

Not really, I reproduced the issue, but didn't look at the root cause. Did it appear with another binary?

All inputs result in the same error.
